Description: CFD (Hypermesh) vs AcuSolve
Product/Topic Name : CFD (Hypermesh)
Are CFD (Hypermesh) and AcuSolve the same tools ?
Based on the tutorial provided, yes u can run CFD analysis with optistruct. Besides, i ran simple case of bending pipe before using AcuSolve and optistruct during 2019. However, regarding ur 1st question, since im not official Altair seller/distributor, perhaps other Community Member will contact/reply to u.
AcuSolve is the solver. Hypermesh CFD is the pre and post processor, where: 1. Pre-processor = set up initial condition, boundary condition, meshing, output data etc. 2. Post processor = Visualize result(s), animate result(s). Other than Hypermesh CFD, Simlab (under Altair) too is a pre and post processor that use AcuSolve as CFD solver.
Is AcuSolve included in OPTISTRUCT ?
In other words, can I run a CFD analysis with OPTISTRUCT ?
SImlab is the multiphysics platform for fluid structure interaction with Altair solvers. SL2420 should be done first, before going to SL2421 (AcuSolve-Optistruct coupling). https://web.altair.com/altair-for-simlab-learning-center-trls
Good luck!
Short answer: HyperMesh-CFD is the preprocessor and AcuSolve is the general purpose CFD Solver. Although since 2023, SimLab is the "default" preprocessor for AcuSolve, gaining all new solver features.
Long Answer:
Altair has 8 CFD solvers (or more depending on how you count). Each of these is specialized for some use case or the other (with some overlap).

AcuSolve : General purpose CFD Solver Altair AcuSolve Datasheet
ultraFluidX: High fidelity LBM (Lattice Boltzmann Method) Aerodynamics of ground vehicles, green house noise and fan noise
nanoFluidX: SPH (Smoothened Particle HydroDyanmics) based for drive train oiling, water management (ingress), tank sloshing, etc.
FlighStream: Aerodynamic solver using panel based method.
FlowSimulator: System level flow and thermal solver on 1D, 2D and 3D levels. Originally developed by GE Aviation.
Inspire Fluids: Design Exploration CFD, with very fast (almost real time) results using voxel based CFD solver, optimized for GPUs (not requiring meshing).
SimLab Electronics Thermal (ElectroFlo) : CFD Solver optimized for electronic thermal applications, with eCAD input and optimized CFD workflow (no meshing required).
AcuSolve and OptiStruct are two different solvers from Altair, with different aims and syntax.
These two can interact with each other for co-simulation (Fluid-Structure Interaction)

Having said, that OptiStruct does include some fluid part on its own (with same OptiStruct .fEM file), however this is limited to Darcy Flow.

As this might be overflow of information, if you post more about your intended application, we could help to identify the correct CFD solver :)
