I am getting a message as per attachment. "The eigenvalue array size has been exceeded . This value may be increased on the dynamics control parameter form. Solution continuing with eigenpairs computed. "
Presently there is no sturm failure. Is it OK if I use results computed as per this ?
To get rid of this do I have to increase frequency array spaces ? If I increase this then the sturm sequence starts failing after a certain number for array spaces. In this case beyond 200 number sturm sequence fails.
Or do I have to increase frequency cut off ?
Please advice at the earliest.
Regards,
Bag piper

To eliminate that error, you must increase the size, as the message states.

The Sturm Sequence Check is just that, a check. This doesn't necessarily mean there is an error or problem with the job. A failure just means there is at least one more frequency within 105% of your stopping frequency. You have to decide if that is important or not.
