Memory resources exhausted， Error in calculating solver matrix CST 2014

Hi,
When i try to run the simulation( CST Microwave Studio 2014), it aborts and give me the following errors:
1. Memory resources exhausted.
2. Error in calculating solver matrix.
Can someone please explain what does that mean and how to solve these errors? Thanks

Hi Sarah,
That seems to be an indication that you require higher memory for your simulation.
Are you simulating an electrically large model? What's your memory configuration of your PC?
