INSUFFICIENT MEMORY ALLOCATED Error for FSI

November 1, 2006, 20:37

I run an FSI between CFX and ANSYS and recieved the following error:

*** INSUFFICIENT MEMORY ALLOCATED *** Action required : Increase the real stack memory size.

For a small number of nodes, the simulation is running well but when I refined the mesh I received the above error.

Is there any one know how to overcome the error?

I use ANSYS and CFX 10 running on a P4 3.0GHz, 1.5GB RAM

Thank you for shareing.

Do as you are told: increase the real stack memory size... Or buy some more RAM

.

How many nodes does your Mesh have?

Thanks Patrick,

My computer has 2GB RAM already and I can not increase since windows 32 bit can only manage up to 2GB RAM.

The simulation that I have trouble with has just only 20K nodes ( just a small one). I can run transient with 400K on my PC but when I run FSI the code gave the warning like I presented. So I think there is some think else when settup the MFX simulation to overcome the "insurficient memory" error.
