Hi all, I am trying to use altair activate to model a system that takes in a signal to control hydraulic valves. The valves aren't the problem but actually building the system is causing me troubles. The system must take the signal and give two different outputs in a sequence that ideally is done using gains. I can figure…
Hi, experts. In the echo file, there are the following items for convergence criteria settings, but what value does the "standard" setting refer to? Specifically, where is the value that corresponds to Standard set? Can it be set in HyperWorks CFD? Also, in HyperWorks CFD, what kind of parameter convergence is being…
Hi, experts. What process is used by the system to calculate "Residual ratio" and "Solution ratio" listed on the web page below? https://2023.help.altair.com/2023/hwdesktop/cfd/topics/pre_processing/solution/plot_run_time_data_t.htm If the model is three-dimensional, the residual ratio and solution ratio are calculated not…
Hi, experts. The items that are output in the end file are summarized on the following web page. https://help.altair.com/hwcfdsolvers/acusolve/topics/acusolve/post_processing_programs_acutranstrace.htm Of these items, could you please explain in detail the difference between "ElmId" and "ElemId"? Specifically, I would like…
Hi, experts. I have two questions: (1) and (2) (1) When I tried to output the Surfaces and Volumes data in Solution > Monitors in HyperWorks CFD using AcuTrans, the following error was displayed. Could you please tell me the cause of this and how to solve it? acuTrans: *** ERROR: Surface_integral_output_vars…
Hello everyone, i'm currently writing a thesis about acoustic simulation using optistruct. Currently i'm studying room acoustics. For this i'm looking at the solutions in frequency domain, but i still have trouble understanding the form of the optistruct solution. I'm trying to make sure, that i don't misunderstand the…
Hello all, When I animate a simulation in Motionview, the duration time of the animation comes from (if I'm right) the print interval and the frames that you animate. How can I adjust the speed of the video to real time? (I mean, that 1 second in the video has the duration of a second in real life). Thanks!
Hi colleges, I have a lot of problems when I'm triying to making rigid groups, in several ocasions, when I want to add different bodies making a group, there are parts that add to it without cklicking them, or some parts are added to other different groups that are created before. In some occasion a lot of bodies was…
Dear Support, We can not see the installation file of the WRAP on the Altair marketplace. I already have the FEKO online machine how can I install the WRAP tool in order to HF communication solutions. Regards
I want to pick the average pressure on specified cross-section of an analyzed fluid model as shown below in Inspire Fluid, but I cannot find how to do this. The version I am using is 2023.1. There might be some option to do this in version 2024, but I would appreciate it if somebody could tell me how to do this with…
