Dear Fellows

I want to import a full mechanism of propane into fluent which contains 78 species and 1800 reactions. However the fluent gives me this error:

heap limit reached. Cannot allocate additional chunks.
Non-character element in list_to_string encountered in critical code section
Mpt_read:failed:errno=10054
Unable to read the cmd header on the pmi context

would somebody PLZ hint me what is the problem?

My system has 8 GB RAM. Is it possible to be caused from low RAM memory?


Best,

Bobi

Hi,
I found this on the net, maybe is helpfull:

In certain instances on Unix and Linux platforms, the heapmemory limit can be reached when:
–Creating a large number of surfaces –Defining a large number of DPM injections
To increase the heap memory allocation, start Fluent usingthe “-h10000000” option
–This will allocate 10000000 storage –The default is 500000

PS: don't know if it's valid for windows also...
PS2: I think it's not related to ram, but with the amount of I/O fluent can handle..

I couldn't implement your hint in windows 7 Operating system. However, I am still trying to fix this error.

Meanwhile, I found this link that may be favourable for others confronting this problem: http://www.eureka.im/1682.html
