I am trying to test the effect of grid senstivity on Fluent. I have a .msh fluent 3D mesh file. I need to increase the number of elements in mesh by 1.5 times and then compute the solution and then decrease the number of elements 0.5 times and then compute the solution. I can't figure out any way to do this. Can someone pleaseeee help me

You have to go back to the software package that generated the mesh.

I don't know which software generated the mesh. We are given .msh .cas and .dat files only

Better ask for a geometry file and build something new from there.
Alternatively, you can try to import the mesh in ICEM. Delete the volume elements and build a coarse, medium and fine grid from the remaining surface elements.
Or try mesh adaption in Fluent. But that will only refine the mesh.
