boundary nodal normal force from a file
boundary nodal normal force from a file
Dear Mr/Mrs. I am new to Elmer. My question is how to apply boundary normal force by a UDF function. The boundary value is from a file. The computation is 3D and the mesh is tetrahedron. A small test shows that the nodal normal value should be give to every vertex in every triangle belong to a boundary patch. The orders of vextexs and the triangles are the same with that in the mesh.boundary file. I am not sure about it. Can anyone can give some advice on this or a piece of code for reference. Thanks a lot. Sorry for my poor English.
