Have a number of tests run with the extended 128 bit precision. Come up with a system where a double/quad precision comparison can be done more easily.

Currently the Bernoulli function, B, is used to do Scharfetter-Gummel.

It would be nice to have an operator that looks something like this:

SG(x, a0, a1) = a0*B(x) + a1*B(-x)

where

B(-x) = B(x) + x

and a function for it's accompanying derivatives

define(SG(x, a0, a1), a0*dBdx(x) - a1*dBdx(-x), B(x), B(-x))

or equivalently

define(SG(x, a0, a1), a0*dBdx(x) + a1*(dBdx(x) + 1), B(x), B(-x))
define(SG(x, a0, a1), (a0+a1)*dBdx(x) + a1, B(x), B(x)+x)

Package symdiff python module with devsim. This makes it possible to experiment with some of the advanced features of symdiff from the same PYTHONPATH

First of all, I want to install DEVSIM in macos (high siera 10.13.6).
I installed python using up-to-date anaconda and then I downloaded the devism_macos_1.4.1.
I set PYTHONPATH var to lib in devsim as below in bash_profile file.

export PYTHONPATH=/Users/odyssey/Documents/TCAD/devsim_macos_v1.4.1/lib

But I faced import error message when import devsim in python.

Symbol not found: ___addtf3 error.

So I'm suspicious of what I installed DEVSIM correctly. Today I found INSTALL file in devsim_macos_1.4.1. Do I have to do something described the INSTALL file ?

Dear, juanesanchez-san. Sorry to bother you many times.

$ pwd
/install/DevSim/devsim-master/examples/diode
$ devsim_py diode_2d.py

------------ diode_2d.py ----------------------------
from ds import *
from python_packages.simple_physics import *

This looks working. However with another test case placed in a different directory.
$pwd
/Application/DevSim/Holor/1stFromSony/devsim_input

------------- input.py ----------------------------------
from python_packages.simple_physics import *
from python_packages.ramp import *

$ devsim_py input.py

----------------------------------- error message ----------
Traceback (most recent call last):
File "input.py", line 4, in
from python_packages.simple_physics import *
ImportError: No module named python_packages.simple_physics

DevSim didn't understand it from input.py description. How can I tell DevSim
where python_packages.simple_physics is ? It seems the only difference is
the directory they are.

I am trying to use load_devices() to restart a simulation but find that the original parameters are missing (all region, device and global parameters are missing).
It seems that the file written by write_devices(type="devsim") does not contain any parameters.
Is it intended? How should I restart a simulation properly? Thanks.

Can I suppress messages from DevSim ? as long as it is running normally.
And can I get CPU time information ?
I couldn't know how to do it from devsim_py -h.

And how can I run DevSim with multi cores ?

Sorry for my many questions.

I think this is caused by a simple misunderstanding, but could you help me ?

Hi,

I was trying to simulate a 3D device using mesh adaptation in a
way similar to that in devsim_bjt_example, but devsim crashes with
a segmentation fault.
I found that this happens when evaluating an element model,
derived either from a node model or an edge model, if the equation
that defines it is more complex than simple additions or the like.
This behaviour is seen only in 3D simulations.
Since I don't know if I made something wrong, I've prepared a simple
example using the same code for both 2D and 3D simulations.
Just run devsim_py test.py dim, where dim is either 3 for 3D, or
anything else for 2D, and see if you can reproduce it.
The same happens if, as an extreme simplification, I replace "sinc"
with the basic node model "x".

Best regards,

Nicola

test.zip

in the API, expose a command for creating an empty edge container. Also make it possible to set these values.

Modeled after:
node_solution
set_node_value
set_node_values

devsim supports version 2.2. Need to provide means to load version 4.0.

relink devsim as dynamic libraries that are callable from any api compatible python interpreter

Sorry to bother you, but I am trying to compile DevSim and met a problem.
How can I define TCL TK paths ?

-- Configuring incomplete, errors occurred!

I remember I had to do 'git submodule init/update' in
/devsim directory, but it didn't improve the situation.

This morning I could do '$yum install cmake28', I don't know
why, but the errors remains as the same as shown below.
About 93% at making symdiff.

no rule to make /root/anaconda/lib/libpython2.7.so
Python.h, import.h,,, are missing.

Oh, I forgot 1 thing. I could not install '$yum install cmake28'
This was the only one thing happened before 'symdiff'.

Sorry to bother you, but I could not make 'symdiff' for CentOS5.1
Here I attached log messages. The errors happened at about 95%
of the entire 'make -j2' process. I had no problem until this point.
Please advice me. I'd like to solve this without upgrading to CentOS6.

The calculation is inaccurate. The correct formula must account for the angle between the edge and the triangle centers on the faces.

For example:

register_function(name="gee",  nargs = 2)

def gee(x, y)
  return x

would become:

register_function(name="gee", func=gee , nargs=2)

or even use a lambda:

register_function(name="gee", func=lambda x, y : x , nargs=2)

Also, maybe inspect the number of arguments to the function:

register_function(name="gee", func=lambda x, y : x)

Sorry, but I need to know right now.

A mesh file has descriptions below. In this case, for example 7116 in
'begin_contact "drain" "Si" "metal"' is the 7116'th node in 'begin_coordinates'
or the 7116'th node in 'begin_region "Si" "Silicon"' ?

I want to install devsim directly in Windows 7 (and not in Cygwin or a vm running Linux). Since there is no Windows binary on the GitHub binaries page, I attempted to install from source. The installation did put directories and files in C:\Program Files\devsim, however, no binaries were generated.
Here are the steps I took:
I downloaded the source from https://github.com/devsim/devsim/archive/master.zip. After unzipping it, I read the Windows.txt file.
Next, I followed its instructions. I installed ActiveTcl, ActivePython, and the Visual C++ redistributable. Next, I set the following paths in path C:\Python27;C:\Tcl\bin;C:\devsim. Looking in the unzipped directory, I observed the Win32.cmake file. I assume Cmake is like make and so I downloaded, installed and then opened the Cmake GUI on the Windows desktop and entered the path to the source and the path to the binaries (C:\Program Files\devsim). I clicked on configure and received the following configuration error: "CMake Error at CMakeLists.txt:5 (INCLUDE): include could not find load file: win32.cmake.cmake". Looking at the CMakeLists.txt, a particular .cmake file is referenced through the ${DEVSIM_CONFIG}.cmake variable to I set this to Win32.cmake. Afterwards, I no longer received the error (but did receive a few warnings). I proceded to generate the build (Cmake build button). The project was built successfully, at least no errors, however, no devsim executable was generated.
How do I get the devsim executable built?
In doc/devsim.pdf, the other dependencies are listed, I assume these must also be installed in Windows:
BLAS
LAPACK
CGNS
SQLite3
SuperLU
zlib
Is this correct?

I simulated and tried to plot /devsim_x86_64/examples/diode/gmsh_diode3d_dd.dat, but Paraview asks me to choose one of (ICM Files, Overflow Files, Omicron Model Input, ParaDis Files,,, so on). Which one should I choose? Or, do I need to install Tecplot?

ACML 5.3 is old. It may be best to move to the system lapack/blas library on each system, or find one another replacement.

I want to run transient simulation with DevSim.
Don't you have any example ?
I tried to modify gmsh_diode3d.py, but I don't know how to do it.

How can I define transient voltage source, start time, end time and intervals ?

By the way, does DevSim use [MKS] unit systems ?

solve(type="transient_dc", absolute_error=1.0, relative_error=1e-12, maximum_iterations=30)
solve(type="transient_tr", absolute_error=1e10, relative_error=1e-8, maximum_iterations=50)
v = 0.1
while v < 0.51:
set_parameter(device=device, name=GetContactBiasName("top"), value=v)
solve(type="dc", absolute_error=1e10, relative_error=1e-8, maximum_iterations=30)
PrintCurrents(device, "top")
PrintCurrents(device, "bot")
v += 0.1

set_node_value has a bug, and will not set the correct value on the node model.

devsim assumes all elements are delaunay. A bad mesh element can result in poor conservation of current, because of the large current cross section introduced. This appears to be handled in Genius using a truncation scheme in 2d:
https://github.com/cogenda/Genius-TCAD-Open/blob/master/src/geom/face_tri3_fvm.cc

For 3d, a similar approach may be used. It would be much more complicated since it would require handling obtuse triangles on the tetrahedron faces. It would also have to handle the center of the circumsphere being outside of the tetrahedral element.

Hello,

The program fails while calling mesh.finalize():

There was a fatal exception in the program.  Shutting down.  Please inspect program output.
UNEXPECTED
Traceback (most recent call last):
  File "resistor.py", line 18, in <module>
    mesh.finalize()
  File "/home/nnieto/DevSim/devsim_gsoc_2018/mesh.py", line 122, in finalize
    finalize_mesh(mesh=self.name)
ds.error: DEVSIM FATAL

The mesh.finalize() method only calls the finalize_mesh() function. I suspect it has something to do with the way I defined the mesh:

# default units are micrometers
mesh.add_line(0.0, 0.01, 'left')
mesh.add_line(10.0, 1.0, 'right')

Parameters are: position, spacing and tag. (Method assumes spacing as positive and default units are micrometers):

    def add_line(self, position, spacing, tag):
        scale = 1e-6
        add_1d_mesh_line(
            mesh=self.name,
            pos=position * scale,
            ps=spacing * scale,
            tag=tag
        )

Any suggestions?

It would be much convenient that we could install with "pip install" command

this will fix runtime path issues
with tclstub, can also makes version independent

Remove EdgeModel data from Tecplot and VTK format. For most models, the averaging onto the nodes is not meaningful. Users should transform models to element models for visualization in VisIt and Paraview
