Error using fscanf Invalid file identifier. Use fopen to generate a valid file identifier. about nemoh HOT 7 CLOSED

Hi,

Perhaps, you could start with the attached files, places the files into your NEMOH source code folder, and try to execute a test case in get_started0.m. Please let me know if you still have the same problem.

Hi, thanks for your reply. I am getting a new error now:
The system cannot find the path specified.
Error using fscanf
Invalid file identifier. Use fopen to generate a valid file identifier.

Error in axiMesh (line 101)
ligne=fscanf(fid,'%s',2);

Error in get_started0 (line 67)
[Mass,Inertia,KHyd,XB,YB,ZB]=axiMesh(r,z,n);% Call the function axiMesh.

It may be because I have put it in a wrong folder, but I am unsure.

Hello there, so I am trying to use Nemoh to find my coefficients for a sphere for use in WEC-sim. I used BEMROSETTA to convert my STL files into NEMOH.dat file for input into NEMOH and then planned to use the coefficients obtained from NEMOH in WEC-Sim for analysis of my device.

However, when I run Nemoh through MATLAB, I get the same error. full error below

Error using fgets
Invalid file identifier. Use fopen to generate a valid file identifier.

Error in fgetl (line 32)
[tline,lt] = fgets(fid);

Error in Nemoh (line 104)
ligne=fgetl(fid);

Error in nemoh_run (line 9)
[A,B,Fe]=Nemoh(w,dir,depth);

Is there any guide on using an already mesh and running nemoh.

Hello @ikaushik007 and @Aayush146
It looks like an error external to NEMOH, check the path and name of the file you provide as input. Matlab simply tells you that he cannot read the file. You should have prior to the 'fgets' command a 'fid=fopen(...)' to tell the code which file you open!?

Best,
G.

Best, G.

fid=fopen([rep,filesep,'results',filesep,'ExcitationForce.tec'],'r');

The above is the line 104 where the error occurs.

And if you display [rep,filesep,'results',filesep,'ExcitationForce.tec'] it is really pointing toward your file?
