Hi everyone,
maybe i have explained too much in my last post. Here i post it again and want to introduce in a simpler way.
You can put ISpan, mesh.dat, boun,dat and disp.dat in the same folder and just run inputfile ISpan. You will get output as shown in output.png. The mesh at the time 0 is as shown in intial.png.
My question is why the nodes of upper right corner have negative displacement in y direction. I think, the right result should be positive.
Best regards
