How to get equal number of nodes and elements in fluent meshing

raghuramswaroop · July 24, 2018, 07:02

I am using a fluid model of a tool to do temperature analysis. But I am getting only 98000 nodes and 480000 elements.

I tried doing the hex and tetrahedron but hex is failing showing a warning that mesh on one or more faces failed and with tetrahedron I am getting quad meshing.

Can anyone tell me how to make meshing to get equal number of nodes and elements with hexahedral meshing?

why would you want that? The numbers never really line up, nor should they. If you have a square divided in 4 equal pieces, you'll have 9 nodes with 4 cells.

Also, there is a specific subforum for fluent questions - it's clearly addressed in the header of this forum to "not post fluent questions here". please move your post to the right location
