      Dear Users Our Commercial and Academic users around the world can use these same forums here as before i.e. the Altair Support Forum , Commercial users from India with solver queries can go to the Solver Forum for India Commercial Users , Academic Users from India and AOC India Participants are requested to go to the Forum for India Academic Users and AOC India Participants , We will be tending to all queries in all the forums promptly as before, thank you for your understanding.

  1. Looks like something is wrong with the model set-up. Please check for surface manager i.e. organizing the surface.
  2. Please follow the steps mentioned:- 1. Open the CAD geometry into Hypermesh 2. Export the same into .nas format 3. Opening the saved file into VWT Check the gif attached with this. Surely, you'll get it.
  3. You can send the files by dragging them or choosing (by providing the path) them...like you shared the last image
  4. Hello Niranjan, Please share your ".hm" file and ".nas" file...will review and get back to you!
  5. It is a bluff body or rather a generic body for performing external CFD test analysis of an automobile. To validate the numerical model with the experimentation, Ahmed body is used in the field of vehicle aerodynamics. Once the numerical model in validated, it is used to design new models of the car.
  6. What is Ahemad Body?
  7. Yes......it is possible to trace. AcuTrace is a particle tracer that runs as a post-processor to or a co-processor with AcuSolve. It can also compute traces for flows on meshes with multiple reference frames in two ways: by converting flow velocities to the local reference frame or by treating the boundaries between stationary and rotating reference frames as interface surfaces and the flow as pseudotransient.
  8. Is it possible to trace the particle in AcuSolve?
  9. First Element Height Total Layer height Growth Rate No. of layers These are generally preferred as mesh attributes.
  10. What are mesh attributes?
  11. Wall, inflow, outflow, slip, symmetry, far field and free surface can be given.
  12. What Boundary conditions can be given in to the model?
  13. Following are the transport models listed below:- spalart_allmaras or spalart Spalart-Allmaras one-equation RANS model. shear_stress_transport or sst Shear Stress Transport 2-equation RANS model. k_epsilon or keps K-epsilon 2-equation RANS model. realizable_k_epsilon or realkeps Realizable k-epsilon 2-equation RANS model. rng_k_epsilon or rngkeps RNG k-epsilon 2-equation RANS model. k_omega K-omega two-equation RANS model. bsl_k_omega BSL k-omega two-equation RANS model. detached_eddy_simulation or des Spalart-Allmaras based detached eddy simulation model. shear_stress_transport_detached_eddy_simulation or sst_des Shear stress transport based detached eddy simulation model. large_eddy_simulation or les Classical (Smagorinsky) LES model. dynamic_model or dynamic
  14. What turbulence models are supported by AcuSolve?
  15. Acusolve is capable of solving 2D using one cell width. So 2d analysis with one cell width is possible.
