Hi. I was trying to simulate motion of a porous cylindrical block inside a cylinder filled with fluid. I am using layering technique for dynamic mesh, and the mesh preview option works perfectly. When I hit run calculation, it throws the floating point error just before the first iteration. But when I run the problem as 2D planar case, instead of axisymmetric, it calculates the solution without any issues and give expected result. Is there something that I'm missing to do which is specific to axisymmetric problems? I have posted the error messages in the console as images below. Thanks

Hello In a 2D axisymmetric simulation, your axis must be oriented along the X-axis (y=0). Is this the case?

OMG. Didn't know there was this limitation. Changing the geometry from vertical to horizontal, with axis along the X-axis, fixed this. Thank you so much.

Perfect!
