I’m having a hard time when I’m trying to mesh a custom FSAE model on SimScale and I’m in need of some help. The full car geometry is the result of me merging multiple .STLs together and creating a master .STL which corresponds to the full car. By doing so, I could upload my geometry on SimScale.
When I tried to create the mesh for my simulation, I came up with this error after the meshing was finished: “Mesh quality report could not be created due to an invalid edge with zero or negative length in the mesh.” This led me to believe that my imported geometry (the master .STL file) was not watertight. I confirmed this by using MeshLab.
After searching online, I came across this page which describes the steps of generating a 3D volume mesh from an .stl surface mesh using Gmsh. However, I’m still not able to create a watertight geometry.
Any suggestions on what else I could try? Maybe I could send the master .STL file to someone to take a look and see if a 3D volume generation is possible? Thanks in advance!
