Hi foamers,

I have been struggling to extract a surface as a patch in an STL file in snappyHexMesh.

I explain myself, I am studying a breakwater and I want to compute the force in specific locations in the crownwall which I import as an STL file (crownwall.stl).

I am using the following code to compute the forces and I need to indicate a patch for the pressure integration :

force1
    {
	type forces ;
	functionObjectLibs ( "libforces.so" );
	patches (SurfaceOfInterest);
	rho rhoInf;
	rhoInf 1;
	CofR (523.5 15 30.693);
	writeControl timeStep;
	writeInterval 1;
	pName p;
	UName U;
	log true;

I don't know if I can do it with just snappyHexMesh or do I have to use TopoSet ?

Iif so I don't know how to use TopoSet, is there a template/model I can use as a basis ?

I have attached the picture of the crownwall with the pink surfaces I want to create to use as a patch for the forces. It's just two squares.

Thanks!

Hi,

Just linking the original post, as it is usually not a good idea to duplicate threads: How to create a new patch in an STL file ?
