Warning during solving the model

Recommended Posts

Dear Sir,


 


During solving my model in Radioss the following warning displays


 


Warning:


The amount of memory allocated for the run is 2093 MB ,which is larger than the specified (or the default) RAM=1000MB,


This run will use minimum core processing in the solver


 


Kindly explain why it shows like these and how to rectify it


 


Thanks

Hi Ramganesh,


 


I am sure that there are someone here to explain it more deeply,but just to inform you;i can say that this is not an important issue and you don't have to rectify it.The warning doesn't affect your analysis results.


Generally,you can get this warning when you try to solve a big model with so many elements.


 


Regards.

Hi,


 


the warning does not affect the results but it does effect the calculation time. The less RAM the solver uses, the slower your calcualtion progress will be.


 


I think with 2039 MB of model size this might be an issue in your case.


 


Generally, to save computation time, use the solver argument -core in, which will force Optistruct to store all calcualtion data in RAM permanently (as long as enough of it is available on your machine)

Dear Florian,


 


My model size is just 67 MB but during solving it shows that is required memory to solve is 2039 MB.


 


I am not clear with statement to save computation time .kindly explain briefly how to do it?


 


Thanks & Regards

yes you are right, i meant "required memory" by "model size", sorry.


 


There are three options available for -core: in, out and min (see Optistruct help -> run options).


 


in is fastest, because the solver does not have to swap data from hd to ram (or vice versa).


 


Just type "-core in" into the solver command line before you start your run.
