i am using CFD 2013 for thermal simulations and get a problem i can't fix.
Setting up a simulation with a parasolid file and configuring all parameters was not a problem.
But then the mesher occurs an invalid point for meshing in the geometry. I fixed this using a CAD program. After that i updatet the CAD in the simulation.
When i want to run the simulation again the following error occurs:
"The simulation cannot run because the design geometry is being updated."
It is also not more possible to update the geometry again. I have to set up a complete new simulation.
So, do you know a solution for this?
with kindly regards
Solved! Go to Solution.
Got a little update to this Problem.
After i tried to update the geometry in an exisiting Design (it was solved bevore) i recieved the folling error window.
Closing CFD and restarting the program bring me back to the satndart problem, were the icon from the designstudy shows an update symbol that won't finish.
Every time this happens, the design study must be set up complete new.
How to solve this?
I have a similar problem. I can’t update a design while it is active in CFD.
When I try to update an active design from CAD with new geometry the Design Study Manager tells me, that it is locked. Other designs of that design study are accessible.
This issue is new to me and came with CFD 2013.
My workaround is to activate another design which is locked then. But the design I’m interested in gets free. Another way is to close CFD.
Is there a solution for this?
I'm wondering more and more. Switching between Design Sudies causes the Program to show more and more different CMD Windows. Trying to close this ends in an closing Program. Otherwise i can wait a long time where only the CMD window becomes updated.
Actually there where 2 Design Studies marked as active. So now I have to delete them instead of changing the geometry.
All this occurs since CFD 2013.
Could you try upgrading your graphics driver? These are all graphic card errors you are seeing in the command window.
i talked to our admin an told him your suggestion. he installed the newest driver and until now the cmd window wasn't shown again.
Here is a screenshot to my first problem.
this occurs after the following steps
-starting simulation and recieving error message from the mesher
-fixing problems in a CAD program
after the update, when i try to start thte solve process this error is shown.
the only way to solve this, is to delete the Designstudy und set up a new one.
I encountered this problem earlier today. I've got a quick and dirty fix for it:
Re export into CFD as a new study & copy your old definitions across.
(You will have to remesh)
Step by step:
- From your geometry in CAD, launch CFD, & create a new design study. Perform any geometry changes as before (it works with edge merge, I haven't tested other geometry changes)
- Save & close the new design study.
In windows explorer:
- Navigate to the old design study
- Copy the following files from the old design study into their respective places in the new design study (replace <Design Study> with your design study names, rename the copy so it matches the new design study name):
<Design Study 1>\<Design Study 1>.bld
<Design Study 1>\Design 1\Scenario 1\Scenario 1.cfdsc
- Open the <Design Study>.cfdst in the new design study
Your materials, groups, BCs, mesh settings etc will be transferred to the new design study and can run!
As I said, quick and dirty.
Hope that helps
