  1. Hi Sourav, Highly appriciate your prompt and detail answer. Thanks!
  2. Hello experts, I am tending to use IS Cast to simulate a casting process of a golden ring. In real-life, they usually made rings by using Vacuum machine for gravity pour casting or rotating machine for centrifugal casting. My questions are: 1. Is it possible to define vacuum pressure in IS.Cast? 2. Can i use gravity-tilt process to simulate the centrifugal casting? 3.Will these features be add to IS Cast in the future? Thank you very much!
  3. Hi Sourav Das, Appreciated for your support. It worked. I need to uncheck "Run at model Location" in Preference >> Inspire >> run options Thank you very much!
  4. Hi, You can try using HyperMesh 2019 with AcuSolve user profile. It supported a lot of functions for AcuSolve and it much easier to use than AcuConsole. Also, in 2019.1 version, Altair released HyperWorks CFD X - very good software. It has GUI like Inspire platform and the way to manage data similar like AcuConsole (use surface group, not like traditional HyperMesh using component).
  5. Hello experts, I am running a casting simulation with IS Cast 2019.2 and faced the error as below image. I tried with 2 other machines and get the same error. Can you explain what issue is this and give me some advices? Thanks in advance!
  6. Hi acupro, Thanks for your detailed answer. i will try it.
  7. Also, when i submit the job to another PC (stronger than mine to reduce processing time) and that machine doesn't have compiler. The solver didn't run and show message as below: does this mean AcuSolve requires the current machine must have compiler? This is quite inconvenience. Since, for large complex model, engineer usually pre-processing on their desktop then submit the job on HPC for solving.
  8. Hi Acupro, I didn't completed Acu5300. But i will share info with Acu4002. They have similar step with compiling UDF file. ok? Below image are the files created after running AcuMakeDLL: The simulation worked, but in .log files, there are messages as below: Can you tell me what is the meaning of acuMakeDll message in .log file? AcuSolve recompiled again?
  9. hi, You can open your run history folder then find the file with extension *.sta. That file is the mesh of the blank after deformed. Once you have the mesh, you can use hypermesh to recreate the surface.
  10. hello everyone, Any update on this post? Does anyone know what is mean of "can not find wave.obj" ? I have faced the same message while compile for UDF file. But the compile process still worked and created new files in the folder.
  11. Hello expert, I have a question about modelling for CFD analysis. As my understanding, for flow simulation, we need to create boundary layer meshing based on velocity, material viscosity, length scale,.. But what if the simulation only have thermal conduction, no flow at all, no Fluid, do we need to mesh boundary layers? If yes, how can we calculate the BL mesh size (first layer thickness)? In OptiStruct, they don't create BL mesh for thermal analysis. Thank you!
  12. thanks Acupro, very detail answer. best regards!
  13. Hello expert, I have a question about a results from AcuSolve simulation. When i post-processing using AcuFieldView, there is a result named "CFL_number" What is this result? and the meaning of it? I have read on the internet and see that is "Courrant number". Is it the same in AcuSolve? Below picture was taken from an AcuSolve tutorial Acu-2000 (Steady State simulation). Thank you all!
  14. Hello guys, I have a question: the porosity result is in percentage: the ratio of voids to solid areas. So what is the Area in calculation? Is it the tetra element volume? Thanks!
  15. Thank you Rahul, i will continue learn about this function. great video. thanks
