Convert results from HyperMesh CFD to Ensight or x3d
Hi experts! I am trying to convert the results that HyperMesh gave me to the ensight format or .x3d. I have seen that ther is a tool to make it called 'acuTrans' that is to translate the AcuSolve solution output to other formats and I have put on AcuSolve this line acuTrans -pb ACU-T1000_Manifold.1.Log -to ensight but it…

Geometry is not showing after importing NX CAD File into Hypermesh CFD
I am trying to import a NX CAD file into HyperMesh CFD. Every time that I do, I am able to click the open button and on the bottom left it says it will load everything and end with "Ready". However, nothing appears on my screen and its just blank. Ive updated all drivers on my computer and tried reinstalling the software…

Hyperworks CFD - How to update mesh and visually confirm new mesh
1. When I import my initial .x_t file, I generate a coarse mesh for it. The mesh below has 3mm large elements * 2. I can run a solution using that mesh, but if I want to refine that mesh to have smaller elements (e.g. 1mm), there doesn't seem to be any way to visually update the mesh to see that it's been more refined.…

Automation HyperMeshCFD Manifold
Hello professionals! Im doing a simulation of a basic Manifold geometry. I want to automate few simulations of the same geometry but with different inlet velocity. I have set the parameter as 'inlet_vel' in HyperMesh and set it as boundary condition. I have made an Excel with the different velocities that i want that the…

I need help with my model. Is it legit?
Hi i need to run cfd and extract Cl Cd in diffrerent AoA. I'll attack all files (mesh, log). This is my volume (chord is 1.56m and span is 0.143m) (aoa 0, vel 108.611 m/s) Ill now attach the mesh condition specified + Now everithing seems fine till i plot Cp/chord. Crazy plts happens also when i plot lift and drag i have…

FSI Analysis (Opristruct - Acusolve) - 3D analysis with structural shell mesh
I would like to perform a fluid-structure interaction (FSI) analysis on a thin metal plate subjected to fluid flow. Since the plate has a thin geometry, I plan to model it using a 2D shell mesh to reduce computational complexity, especially in terms of resolving the plate's thickness. My goal is to maintain the fluid…

How to simulate quenching of an aluminum profile?
Hello everyone, For my master’s thesis, I am currently conducting quenching experiments with aluminum extrusion profiles. The profiles are heated to 550°C and then quenched in a water bath. The profiles are always submerged exactly 90 mm deep, with the water column being 120 mm high and the water temperature set to 20°C.…
