Hi All,

I have a solidification simulation with dynamic shrinkage model and microporosity model activated. Shrinkage seems to be ok, but the calculated Microporosity is about 1.E-10. Has someone experience with this combination?

what version of FLOW-3D are you running? there was a problem like that, I think, in version 9.3, but has been fixed since then.

I'm using version 9.4.1, running on linux 64bit.

We have verfied the microporosity issue now with different setups. It's now clear that the micro- porosity is only calculated correctly (in combination with the solving of the momentum equations) when shrinkage is deactivated. That's not good, because we would need dynamic shrinkage AND micro- porosity...

Hi Johannes,

I am Ken, studying in germany. I am currently writing my bachelor thesis with flow 3D 9.4.1 as well. I am simulating solidification process. But I have some problems with the display. It doesn't show shrinkage on display and the temperature variation is illogical and the pressure variation doesn't change at all.

May I know what settings did you make for this solidification simulation?

I do not know where the problem is and i am using copper as my mould and pure iron as my fluid 1.

Thanks a lot first for ur attention and time.

best regards
