Error ?

Orb · February 8, 2012, 13:18

What does this error mean:

ERROR #001100279 has occurred in subroutine ErrAction. |
| Message: |
| SYMASS_ZIFCS_EL : The solver ran out of temporary space while bui- |
| lding a linked list for a domain interface. Try setting the expe- |
| rt parameter "topology estimate factor zif" to a value greater th- |
| an 1.0. Values higher than 1.2 should not be necessary.

I tried values of 2.0+, but still the same error... Could anyone take a look at my model? Thanks!

The error is saying it is having a hard time assembling your interface. I would remesh and try to improve the mesh quality around the interface.

stumpy · February 8, 2012, 16:44

Make sure you really did set "topology estimate factor zif" and not a very similar parameter that is in the GUI. I think you have to set "topology estimate factor zif" via CCL.

Orb · February 8, 2012, 18:03

How do I get to CCL?

I went to "Expert Parameters" then "Convergence Control" Then checked "topology estimate factor" and set it to 2.0. Is that the right one?

Orb · February 8, 2012, 22:24

Ok, I got it to solve without errors. But now my results show no motion even though I have a rotational device inside of a fluid... but nothing moves..

ghorrocks · February 8, 2012, 22:31

Is it a steady state or transient run? Have you run it long enough to see motion? Is the rotating bit transient rotor-stator of some other form of motion?

I would like it to be transient, although I'm not aware of how to enable that. It is basically a fan inside a tube with open ends and the whole thing is in a domain of fluid (air). I want the fan to distribute the air and test the performance.

ghorrocks · February 9, 2012, 06:22

Well of course if the simulation is steady state then nothing is going to move at all. Doesn't that explain the lack of motion?

Yeah, but the results are all zero.

Can you post an image of the results and what you are trying to model?

I assume the fan rotates and generates a flow. What is the interface which caused the initial problem? Can you post your CCL?

Orb · February 9, 2012, 18:28

Sorry, how do I get to the CCL?

Is this it?

No, the CCL is the stuff in the first section of the output file - the bit you chopped off.

But I can see you have three domains and do not appear to have any interfaces to connect them. Also your fluid domain does not have a temperature/heat equation so cannot be linked to your solid domains.

Looks like you have made some pretty basic setup errors with this simulation. I recommend you do the tutorials on conjugate heat transfer, that is ones with solid and fluid bodies coupled together.

Orb · February 10, 2012, 00:07

Thanks!

I actually did the Ch 17 Tutorial: Multiphase Flow in a Mixing Vessel...

It was helpful, but actually confused me quite a bit. Do you have to model fluid around the propeller and fluid inside the tank separately? That part confused me... How many components do I need to solve my problem? Just the fan, tube, and fluid... so 3 parts?

ghorrocks · February 10, 2012, 00:12

Do some of the rotating machinery tutorials to see how you model rotating devices.

Orb · February 10, 2012, 00:41

I think I have it now -- BTW Ch 17 is turbomachinery tutorial

But I can see you have three domains and do not appear to have any interfaces to connect them. Also your fluid domain does not have a temperature/heat equation so cannot be linked to your solid domains. Looks like you have made some pretty basic setup errors with this simulation. I recommend you do the tutorials on conjugate heat transfer, that is ones with solid and fluid bodies coupled together.

Orb Member Join Date: Jan 2012 Posts: 52 Rep Power: 14	Thanks! I actually did the Ch 17 Tutorial: Multiphase Flow in a Mixing Vessel... It was helpful, but actually confused me quite a bit. Do you have to model fluid around the propeller and fluid inside the tank separately? That part confused me... How many components do I need to solve my problem? Just the fan, tube, and fluid... so 3 parts?
