Error allocating requested memory
Error allocating requested memory
(OP)
I have an old version of Algor Fempro (13.38 Jun 03) which I am installing on my newest computer, XP O/S. My modeling package is AutoCad Mech Desk Top.
Modeling, meshing and boundary conditions all go well. The problem occurs when I attempt a solution. After a few seconds I get and error message: "Error allocating requested memory". I am currently using just a small model to trouble shoot the problem.
My Algor service contract has expired long ago and they can offer no help. I am hoping someone on this forum will have a solution. I have more than adequate computer memory, espically for my small test model. I have also double checked the various environment variables.
TIA

RE: Error allocating requested memory
I just recently went through a problem with algor about memory. During analysis right after the sparse solver was activated I would get an error (see attached file) saying it was out of memory. I must digress and say that originally I had 4GB of ram then we added 16GB more. When I had 4GB of ram I would not see the error but after I added the 16GB of ram I would get the error. It turns out that algor will only support 8GB of Ram. If you allocate more to algor you will get an error. I do not know if this is your problem because you are running 13.38 and I do not know if you have more than 8GB of ram but if you go in and reduce the amount of memory allocated to the solver you will not see this error (if this is indeed your problem). Hope this helps if not hope you solve your mystery.

Care to fill in some additional specifications, rtarozzi?
RE: Error allocating requested memory
First of all the machine is x64 and I have 2GB of ram. It turns out that my problem stems from confusing my MB's and GB's. In 'Environment Variables' I assigned too much memory to ALGMEM, more than I actually had. Therefore the program could not "allocate the requested memory". Fair enough. The values in 'Environment Variables' are KB's not Bytes and I was entering too many zero's. Ultimately I assigned approx 80% of the available memory, 60% of the total memory, and I was able to obtain a solution for my test model. I am not sure what will happen when I attempt a larger model. I believe what will happen is that Algor will page out to the disk and the run time for the solution will be longer. At that time I will just purchase additional ram.
Thanks again for all your effort(s) I really appreciate the help. I am always amazed at all the help that is "out there" if you just ask.

I am using XP64 with 4-GB of RAM. Please could someone explain to me how I can solve this problem?
I do not know how to access the 'Environment Variables' concerning Algor; neither do I know how to alter anything to do with ALGMEM.

I would still like to be able to run ALGOR within XP-64, of course.

However, one way around this was to install VirtualBox, which allowed me to install the 32-bit version of XP within the 32-bit (an OS within an OS running as any other application). Within this 'virtual' 32-bit OS I am able to use ALGOR properly.
This is not satisfactory as I would, ideally, like to use ALGOR within the 64-bit OS. But when I try I get the 'Error allocating requested memory' message and the analysis fails.
The thread starter had the same problem, but was able to solve it. I would like to know exactly how.
