Long opening time

I have a FE model. When I want to open this model in my CAD computer, opening time is more then one hour. I noticed that when I set Performance Graphic to OFF in Preferences, to opening time will about 8-10 seconds. When I set Performance Graphic to ON after opening this model, Femap will not responding long time (I didn't wait, how long, I shut down Femap with Task Manager).


My computer:


Windows 7 Professional 64-bit

CPU: Intel core i5-4670 3,40 GHz


VGA: NVIDIA Quadro K2000


I use Femap v11.2.

Re: Long opening time


Hi Peter,


There is a Read/Write Test that you could perform to let Femap select the appropriate Open/Save method for your computer. You will may be notice a difference !

Dear Peter,

This is a problem related with POWER GRAPHICS, the FEMAP V11.2.1 developers are working hard in improving the Performance Graphics option in FEMAP but still has some performance problems (I have reported a few related with CHEXA 20-nodes elements), soon we will see a full revolution in postprocessing in FEMAP, meanwhile you can set OFF performance graphics in FILE > PREFERENCES > GRAPHICS if you experience problems. Also I suggest to send copy of you FEMAP model to SIEMENS GTAC (  to let them to know the problem and improve FEMAP.


But make sure to have activated VERTEX BUFFER OBJECTS option, this is critical for rotating your model, in the options set the VIDEO RAM of your graphics card k2000.

Hi Blas,


I doesn't have a right to GTAC (I'm not an System Administrator), therefore I can't send my model.

I made a read/write test, the Open/Save Method was changed from 0..Windows I/O to 3..64K C I/O, but the result is the same. I shut down Femap after 20 minuts.

In Graphic Preferences I earlier set the VERTEX BUFFER OBJECTS.


Best regards,

What graphics card is in the machine which works properly? If it is also the K2000, then I would suspect the driver is out of date on the machine with problems. Updating the driver will likely correct the issue.

If you have 2 different cards in the machines, please let us know the configuration of both machines.

Sorry I was wrong. This model doesn't open in my other computer with Performace Graphic ON neither.


Details of this computer:


Op. system: Windows 7 Professional 64-bit Sevice Pack 1

Motherboard: DX79TO

CPU: Intel Core i7-3820 3,6 GHz

RAM: 32 GB

VGA: NVidia Quadro 600

Thanks for providing the model. Our graphics expert found the issue with the Performance Graphics; it was an infinite loop when you had nodal or elemental thermal loads in layers that were not displayed. This is fixed in our next release. In the meantime, a workaround would be to display all layers, or at least the layers where you elemental or nodal thermal loads. You can use Group/Operations to create groups from your layers and then use groups to control what parts of your model are visable.
