Hi,

I am trying to do a thermal comfort simulation in an office. Analysis type is steady state. The office has 7 rooms as shown in the picture. First I just simulated 2 rooms and I did not get errors. Then I made the other rooms and I got the following error message. There are air conditioners in every room. The model include thermal radiation on the window boundaries. I use ANSYS 16.0.
Can anybody help me with this error?

Looks like the partitioner ran out of memory. Try using the large simulation partitioner.

[Gwandel]

I tried now but I get the same error.

[ghorrocks]

There are plenty of other options to try. Try different partitioning algorithms. Also read the documentation on the command line options for available options with the partitioner.

How many nodes is this mesh?

[Gwandel]

Nodes: 4080647
Elements: 14351488

[ghorrocks]

That is not a large simulation. There is some other problem with your simulation setup. A moderate size model like that should partition fine. I would check your simulation setup.

Not sure how you obtained your definition file, a previous version ?

From the message, the software is failing when accessing the database (DB) for the definition of mesh regions (REG MAP).

Does it fail if you try to run in serial mode ?

Hope the above helps,

[Gwandel]

Thanks for the help so far, but it also fails in serial mode.

From your CFX_001.out, the message says it all

Couldn't initialise lpnquery library

Something must be wrong with the definition file. Try writing a new definition file, or re-importing the mesh.

Hello,

I am trying to solve FT TRb rotor-stator case for flutter analysis. In past every thing was good. but recently I am getting this error.

I had trying multiple things like increasing memory over riding memory etc.. tried in serial mode, but same results. can anyone help suggest me anything, please?

[ghorrocks]

Please do not PM me with copies of posts on the forum. I find that extremely rude.

I had the same Error-Message and tried many things with no effect until i found that other topic. For me it was a hidden "ä" in a Sectionname which I completely oversaw Maybe the last answer there can help others too. -> lpnquery error

[Martin_Sz]

Hello
Try using serial mode
And i have a question how many finite element have Ur model ???
