[ANSYS Meshing] Problem with meshing large model

s.sunilkrishna · February 3, 2015, 04:35

I'm working on a project which has one acre pond and large number of piping connections. The pipe size vary from 0.5 inch to 4 in dia.

I need to do multiphase modeling of air and water interaction from the porous pipe n water in the pond.

I have done modeling in design modeler n performed Boolean operation to subtract the pipe from pond and then filled the hole area to form pipe.

I'm not able to generate mesh even if I give small element size. It says to change the element size or apply virtual topology. Can anyone help me out with this prob?

Could you post your geometry to give us a better idea, why and how it is failing to mesh?

Cheers

Pls find this link for step file geometry ( https://www.dropbox.com/s/xq76f7tpp6...ystem.stp?dl=0 )
Let me know if there are any issues with the geometry and whether the mesh is getting generated or not.
