Insert data of existing Flow Field

Zerzura · November 5, 2015, 04:47

Goodmorning/afternoon/day,

I have a problem with solving my simulation of drug distribution in the arterial wall. The solution is not converging when I solve both the velocity profile and the User Defined Scalars (UDS) at the same time.

Therefore I want to first solve the velocity profile and use that velocity profile to solve the UDS distributions.

My plan was:
- solve the velocity profile
- load .cas and .data file
- add the UDS and source terms
- turn of the function at: solve/solution-controls/equations/flow
- get a fully converged distribution of the UDS and maintain the flow field

However after running the simulation again, the flow field has changed drastically.

Please can someone give me advice how to implement the flow field and not let it be changed afterwards?

Your help is much appreciated.

I think you should already have it, your approach should work. Are you running this remotely on a cluster? You might have given the wrong commands. You TUI commands you should be using are:

/solve/set/equations/flow n

Also remember to disable any turbulence, temperature, etc. Check to make sure you actually turned off the equations properly.

thank you!

I made another mistake, it was not loading the data-files correctly

.
This method is correct however
