  1. Hi Rohit, You can define the mass flux BC at the inlet and define the pressure at the outlet BC and simulate it. You can also define the above and in the advanced options, you can assign the pressure at the inlet as well, its not advisable to do so. May be we can have a web meeting accordingly, to review your model. Let us know your convenient time. Regards, kamlesh
  2. Hi All, Please find attached tutorial for CFD optimisation of a manifold. Some of the applications, where it can be used includes, HVAC ducting • Reduce pressure drop • Increase flow uniformity • Maximize/minimize outlet temperature Heat exchangers • Maximize pressure drop • Maximize heat transfer Brake discs • Minimize temperature • Maximize heat transfer • Brake cooling ducts External Aero • Minimize drag • Maximize negative lift and many more. I have also attached a simple Pipe CFD optimisation tutorial. Please do contact us for any queries. Regards, kamlesh Acusolve_Hyperstudy_tutorial_manifold.zip Acusolve_Hyperstudy_Tutorial_Pipe.zip
  3. Num Krylov vector

    Hi Dinesh, You are welcome. Please do let us know for any further CFD queries. Regards, Kamlesh
  4. HM CFD Overview

  5. Hi All, Click here to view a webinar on Nanofluidx capabilities Regards, Kamlesh
  6. Num Krylov vector

    Hi Dinesh, The krylov vector is used in the linear equation solver (GMRES), wherein you need to compute a base vector for the krylov subspace, in which the Euclidian norm of the residuum is minimized. The problem is, that you need all base vectors from previous iterations to compute the base vector for the current iteration, which is an expensive operation for solving. As the costs and memory increase linear with the number of iterations, it’s usual to drop the computed base and restart the iteration with the current approximation. The number after which the iteration gets restarted is the number of krylov vectors you define in AcuSolve. And this number determines how much memory you need for your computation with AcuSolve. Regarding convergence, a krylov vector which is too small can affect convergence negatively (in difficult cases), but at a certain level a higher krylov vector won’t improve the convergence anymore. If the problem had difficulty converging, this will/may help. If it is converging well, it does not help at all, and perhaps makes the solution a little more expensive. As a general rule, use 10 and perhaps 20-40 for the Flow thermal coupled system (Natural convection). Please refer the AcuSolve manual for more details as well. Regards, kamlesh
  7. Modeling multiple exits

    Hi Pradeep, Lets have a web meeting today at your convenient time. I need to understand the experimental set up and make sure the same is followed for the CFD simulation in AcuSolve. Let me know your convenient time today. Regards, Kamlesh
  8. Dear All, Both AcuSolve (CFD) and MotionSolve (MBD) Hyperworks Solvers can be coupled, cosimulation is possible. Certain Applications being real time Aerodynamics simulations, Wind turbines, Fuel tank sloshing, Pressure check valve etc. Click here to view the webinar on AcuSolve (CFD) & Motionsolve (MBD) coupling Attached is a tutorial on the same coupling - Pressure check valve. Regards, Kamlesh CFD_MBD.zip
  9. Dear AcuSolve Users, Please find the detailed procedure of mapping AcuSolve CFD results through linear interpolation option. It has a python script attached, a pdf document explaining the process to be followed. This Script can be utilized to get all the CFD results like Velocity, Pressure, temperature etc and map it onto other mesh for further analysis. Regards, Kamlesh Script.zip
  10. MultiPhase Simulation of Pump

    Hi Pradeep, As discussed over the phone, we shall get back to you on this query. Thanks. Kamlesh
  11. Dear AcuSolve Users, Please find the attached material to run AcuSolve in batch mode. Regards, Kamlesh BatchRun_AcuSolve.zip
  12. Acufieldview

    Hi Rohit, In AcuSolve command prompt, read your present working directory, please use the below command. acuTrans -pb <inp file name> -out -to fieldview This will write fieldview files which can be used for post processing in Acufieldview. (*.fv and *.fv.reg) In Acufieldview, Read the *.fv file. Regards, Kamlesh
