exporting mesh from hypermesh to fluent

Recommended Posts

hey, i am new to hypermesh and i want to create mesh then export it to fluent, while the mesh is being exported successfully i face problems when i run the fluid simulation. i see the analsysis for only 1 mesh thickness and the flow is not going any further . i created a simple geometry to test my hypothesis. i suspect there is a problem is treating the body as fluid, kindly guide me.

geometry is imported with mesh in ansys.JPG

you need to define 1d elements on edges. You can extract these edges by finding free edges. Then move those 1d elements to inlet, outlet and other component which can be used as boundary.

Details of the modeling is there in help: http://www.altairhyperworks.com/hwhelp/Altair/hw13.0/help/engsol/engsol.htm?export_for_cfd_solvers.htm
