Workbench 16.0 - Memory Allocation Factor
 

Hi there!

I am currently working on Ansys 16.0 Workbench with the student's license and I need to ask you something. Each time I am trying to start Solver with my project error occures:

Illegal data area length CDANAM = NCOMPT CDTYPE = INTR ISIZE = 0
CRESLT = SIZE

Current Directory : /INTERP/SOLUTION/DST/VX

On some websites I've found that this problem is connecteed with my computer's allocated memory and I found info that to overcome this problem I have to adjust the memory configuration. In Ansys help viewer I found this information.

Memory Allocation Factor: Use this method to modify the memory allocation for the CFX-Solver step as a whole. For example, a value of 1.05 for Memory Allocation Factor increases memory allocation by 5% and a value of 1.1 increases memory allocation by 10%.

My main problem is that I can't find those options in Workbench 16.0. I've looked up the internet and there are only results for lower versions like 8.0, but they are not working with mine.
Can you please help me with this?
Thanks

When you are in "Define Run" in Solver Manager before you start your calculation, you have to check "Show Advanced Controls". After that, you have more tabs available, e.g. "solver". You can change the "Memory Allocation Factor" here or select and edit "Detailed Memory Overrides"

Thank you very much for your help. Now I know where to find it and it helped me when I changed this setting, I still however can't see the big difference when changing from 1.0 to 2.0 for example, but fortunately it cancelled my error

Thanks for the feedback. I don't know why CFX can't handle that alone ('take as much as you need from my physical RAM').
I usually use factors like "1.2x" (see the 'x') instead of '2.0' - read up on the difference in the documentation in case you're interested :)
