An-out-of-memory error

[AleksaBgd94]

Hi everyone,

Abaqus exited with this error:

8 nodes on an embedded element do not lie in any host element. Check coordinates, exterior tolerance and absolute exterior tolerance parameters, and the host element definition. The nodes have been identified in node set ErrNodeEmbeddedNode.

2378 elements have missing property definitions. The elements have been identified in element set ErrElemMissingSection.

***Error: An-out-of-memory error occured. If you have access to a machine with more physical memory, you can try running the application there.

I really can't realise where my mistake is because it was pretty simple to define embedded region and host element.

If you have any idea or need more information please write.

Thanks in advance.

2378 elements have missing property definitions. The elements have been identified in element set ErrElemMissingSection.

I managed to solve this error. The reinforcement was defined as a beam-truss element in property module, but not as a truss element type when I defined the mesh.

I still can't cope with the first error.

Right click on your job in CAE and select Edit.

There is a "memory" tab in the window that appears. It allows you to specify the memory allocation for the job.

Is your model huge? If not, have you tried restarting your machine?

Hi Dave442,

thank you for your help.

When I defined reinforcement's mesh properly and defined embedded region constraint again after that it all worked out fine.
It seems that Abaqus was a bit confused because of incompatibility of section property and mesh property...

I think my model is pretty huge. There are a lot of finite elements in the model and it takes too much time for my computer to calculate this detailed model. And ODB files are usually about 6-7 GB.

to reduce the size of your model can you reduce the mesh or exploit symmetry or planar conditions?

alternatively, if you have the resources, can you run the analysis in parallel?

Unfortunately , I can't... but does Abaqus run faster the anlaysis with hex element shape instead of tet element shape?
Beacause it's the only thing I can change in my model.

 

[FEA way]

Hexahedral elements have more nodes and thus more degrees of freedom. They won't be faster but conversly - the analysis will run longer.
