Hi there
May you have any advice how I can create an input file which can be used by Ansys for further analysis?
My aim is to set-up a script to parametrise my model and then automatically alter all the parameters and execute the analysis in Ansys.
My initial draft from last year is generating an ABAQUS input file, but I couldn´t find any information how I can import into Ansys.
Example of my draft (Matlab + main file) and the import of the rolled-up structure in ABAQUS attached:

Please copy and paste the code here, as the image is not clear.

Thanks, @Dyuman Joshi
Code in Matlab:
file=fopen('nodes.inp','w');
fprintf(file,'%12.f, %12.8f, %12.8f, %12.8f\n',nodes');
fclose(file);
file=fopen('elements.inp','w');
fprintf(file,'%12.f, %12.f, %12.f, %12.f, %12.f, %12.f, %12.f, %12.f, %12.f\n',elements');
fclose(file);
file=fopen('sets.inp','w');
for i=1:1:length(sets)
fprintf(file,['*Elset, elset=set',num2str(i),'\n'],elements');
fprintf(file,'%12.f, %12.f, %12.f, %12.f, %12.f, %12.f, %12.f, %12.f, %12.f, %12.f, %12.f, %12.f, %12.f, %12.f, %12.f, %12.f\n',sets{1,i}');
fprintf(file,'\n');
end
fclose(file);
Code in main:
*Node
*Include, input=nodes.inp
*Element, type=C3D8
*Include, input=elements.inp
*Include, input=sets.inp
