Dear FreeFEM users,

I have tried several formats of “mymesh.vtk” using the following code, and all failed

load “iovtk”  
meshS ThS=vtkloadS(“mymesh.vtk”);

Can someone please provide a simple example of “mymesh.vtk”?  
Thank you very much in advance!

Best wishes,  
Yongxing.

Possibly the vtkloadS is boggus but I don’t not,

this peace of code build a vtk file

```
load "iovtk"
load "msh3"
meshS Th=square3(10,10);
savevtk("Th.vtk",Th,bin=0);
meshS ThS=vtkloadS("Th.vtk");// “mymesh.vtk”);
```
