Overwrite Values each n-th time step
 

Hey everyone,

Got a question:
Is it possible to overwrite a solution of a object each n-th time step?
More accurate, I have several objects in my calculation grid, and i want to "copy" the values of object 1 to object 2 and so on...

Thank you in advance,
Cheers

Can you explain a bit more so we can try to help?

Yes of course,

I want to model the warming of steel slabs as passing through a furnace. The steel slabs are therefore shifted every x seconds. So, the steel slab on position 1 moves to position 2 and so on.
So, when I am performing a transient simulation is it possible to copy all Information from one steel slap to another each x seconds. I know in transient simulations it is possible to write data with "Automatic Export", but is it possible with an udf, so i do not have to do it manually?

cheers

You can use UDM to storage whatever the information you want. Use an DEFINE_EXECUTE_AT_END so at the end of each iteration (or time step if transient) it will storage the variable you want in a UDM. Later you can set the UDM value to the profile/variable you want.

Thank you very much.
Maybe other questions arise later ;)

cheers

Hello,

another question arised. The method with the UDM seems great, but in my case i have more than 500 cells, so the memory will be exceeded. Is there another possibility to transfer the data and maybe modify during the transfer?

Thanks in advance,

Cheers

I use UDM with more than 40 million cells, so it is hard to believe that you run into problems with 500 cells...

I'd say the same. I work with over 40 UDM and 1.2mi cells and had no problem at all. I think either there is a misunderstanding from your part or you are doing something wrong that is causing the loop not to stop running and is overloading your memory.

Apparently I misunderstood something.
Thaks for your help

cheers
