I am finalizing this project and getting ready to run the final parametric study and I am having trouble getting the model to rebuild (I suppose that's what's going on). In my parametric study, I am able to pick up my GV. Parametric study is running as a "what if" type, and all my design points are set to "recalculate" to force a new mesh since the geometry is changing for each DP.

I'm completely new to Flow Simulation and despite having spent a day reading the online tutorial and watching examples on YouTube I'm having trouble extrapolating to my study case. We have air flowing through the flexible coolant at an arbitrary rate and argon flowing through the container next to the coolant at a 13L/min.

Why Soldiwork Flow 2015 solve too slow at 29% CPU(12core), 27/56 GB Ram with 7929089 fluid cells, 4026792 Partial cells? Older versions of Flow Simulation utilize multiple cores for solving at a lower efficiency than newer releases. This is due to the overhead of having to split the calculation into several pieces to then pass out to each threads of the CPU.

Local Mesh I am trying to model thermal boundary layer in between fins and I am wondering what's the best way to mesh this problem.

everything is working nicely, and I am currently working on several design parameters, remeshing/resolving - the default convergence criterion isn't great, and found that looking at the average temperature on the outlet LID of my fluid subdomain not only is a good indication of when convergence is reached (asymptote) but is also one of the better performance indicator for this analysis. So I've added this average temperature as my only goal. If in the "calculation and control options" I select "

This is a based-transient analysis, but it could also be solved based on parameter-driven methods. I would like to have a flow through a chamber that has two outlets. One outlet vents to the atmosphere.

Ever since the system got upgrade to 2017, the flow simulation never worked properly. Always crashes. c). do flow volume check, sometimes showed volume, sometimes showed no volume, although nothing is changed

I'm pretty new to flowsim and currently having many problems regarding all kinds of errors. Geometry check is fine in the model below, though there is some threads interference (screws and nuts). The face of boundary error is blue highlighted in the image (inlet flow). What can possibly go wrong and how can I address it?

Hello everyone, my name is Marco, I'm a Mechanical Engineer to be and I'm currently working on a ball valve project. This valve works with water so I'm verifying the cavitation model and here occurs my problem: I'm running a simulation and at 1000 iterations (0.125 travel) it doesn't cavitate yet, even though there's a strong deltaP between inlet and outlet and I'm sure it has to cavitate. I know it is not a whole travel, but with all the other cavitation projects I did, the phenomenon started

Gravity Gradient- Flow Simulation I was wondering if it is possible to create a formula for gravity in the Flow Simulation dependent on X,Y, and/or Z. I know that you can have gravity change over time, but I would like to have a gradient of gravity applied to my model. This is flow model is almost completely driven by centrifugation and a few flows, so having the gradient is important for this model.

I have a flow simulation completed and am trying to estimate what overall heat transfer coefficient flow sim is giving me for a finned surface. Unfortunately, I do not have a surface that has the correct cross-sectional area that I want to base my U on. (I tried adding a part that is just a surface to the assembly, but the surface plot failed - probably because the surface wasn't defined before the simulation was run.) So, I created a patterned point-parameter table w/100 points which I then

I'm looking for some some help interpreting my results and making sure they are correct. I'm running a flow simulation where my volumetric flow rate in is 1 L/min and my exit is a pressure opening at 0.5 MPa. The fluid is flowing through a tight, rectangular restriction of 0.005 mm height and 72 mm width. I'm using a local mesh with equidistant with a 0.05mm offset distance and checking for mesh convergence by increasing the refinement level.

I've been running flow simulations lately so I have a lot of files created by these simulations. I made a list of all the file types that I have littering the PDM (but not checked in) on my computer. I have many GB of data from old simulations that I need to either check in or delete and I'm looking for information on what each file type is. If I only want the ability to rerun the simulation later what file types do I need to check in?

To report back, the issue has been solved and Response Surface Viewer works again on my SW2018 SP4.0. " After investigation, this issue is due to the SW installer. The program “CqmViewer.exe” is absent in the “C:Program FilesSOLIDWORKS CorpSOLIDWORKS Flow SimulationbinCFW” folder after installation."

After setting, computational domain, mesh, Goals, etc and save them I run the part that is open. Then I want to open another part and run it with the same settings Under the Projects Tree, you can right click on the simulation you want to clone, and then click clone, and then choose which configuration you want to clone the simulation to.

I haven't used flow simulation in about two years, but it seems the latest iteration that I am using (2017) no longer allows for exporting the results mesh data to excel? I used to be able to export based on fluid cells, partial/solid cells, but either I can't remember how I did that previously, or the functionality no longer exists (which would be a real bummer). Now it seems I am only able to export the mesh data to a text file which does not export well to excel (columns get all messed up).
