Attachment 17285Hi

I have problem, solver code give :

+--------------------------------------------------------------------+
| *** INSUFFICIENT MEMORY ALLOCATED *** |
| |
| ACTION REQUIRED : Increase the character stack memory size. |
| |
| Details : |
| Requested space : 2280000 words |
| Current allocated space : 1597440 words |
| Current used space : 3000 words |
| Current free space : 1594440 words |
| Number of free areas : 1

like I understand it is required increase word size in attached table

I have try with 3m setting but result was the same...

thanks for help

You are changing the settings for the interpolator. Isn't it crashing in the solver?

Also you are changing the settings for real memory not character memory. It is crashing due to lack of character memory.

And I would recommend using the "2x" approach to specify the memory, not an absolute number. This just allocates twice as much as it previously guessed.

Running out of character stack is very unusual. You must have some weird object names in there.

Thank You all for quick reply,

Glen what do You mean weird words?

for calculations I used Lithuanian words for separate names selections
like intake or outtakes ....

but it does not make any problems until I used double precision

Are you using any special characters, or it the names very long?

Not to worry, if it can be fixed by just using 2x character stack space then ignore the problem and just proceed. It is not worth the effort to work out what is going on.

I used 2x and now it woks!

thanks for all
