Mesh in Hypermesh, solving in AcuSolve

Recommended Posts

Hello everybody,


i have the following problem. I generated the CFD - Mesh (quater of a pipe) in HyperMesh (as you se below) and exported it to AcuSolve ( file type: .inp and .asm).



In AcuSolve i set the following parameters / Boundary Conditions:

Inflow: Average Velocity: 0,2 m/s

Outflow: Pressure: 0

Wall: Wall Condtion, with standrad Wall function

Sym_xy: Boundary Conditon Symmetry

Sym_xz: Boundary Conditon Symmetry

CFD_tetcore001: Material = Water


Problem Discription:



Auto Solution Strategy:



When i start the simulation, the results have nothing to do with reality.


There should be a preesure drop from inlet to outlet around 15-16 Pa.


But this are the results: image.thumb.png.7b0ff576ca1d8d645a641addd2f74663.png



But the thing i don't understand is, if i build the model completly in AcuSolve, i get the right result by 5 percent deviation.


When i start the simulton in Hypemesh a always got this warning:  "WARNING: Multiple command issius"

Or i got the wron results.


Please,  could you help me

I got the Answer from the support. The Dimensions weren't right. I build die model in NX11.0 and importet it in HyperMesh. So die Unti was "mm". After i scaled the model. I got the right results.
