Convert ICEM CFD mesh to COMSOL-compatible mesh

Dear altruists,

I have created a mesh on ICEM CFD and used it in simulations using Fluent and OpenFOAM. But now I need to use that exact mesh for COMSOL. I am new to COMSOL and found that there isn't any straightforward way to import that mesh. Some communities suggested converting this to NASTRAN format, but I can not find any option to export the mesh to that file format. Is there a way to convert this ICEM mesh to be imported on COMSOL?

Thanks in advance.
