# SOL 200 Problem

## SOL 200 Problem

(OP)
Hello all,

running the script below, I'll get the user fatal messages:

*** USER FATAL MESSAGE 316 (IFPDRV)
ILLEGAL DATA ON BULK DATA ENTRY DRESP1
DRESP1 1 FRMASS FRMASS
*** USER FATAL MESSAGE 316 (IFPDRV)
ILLEGAL DATA ON BULK DATA ENTRY DRESP1
DRESP1 2 COMPLI COMP
*** USER FATAL MESSAGE 307 (IFPDRV)
ILLEGAL NAME FOR BULK DATA ENTRY TOPVAR

Does anyone know, how to correctly implement TOPVAR and DRESP1 into the script?

Kind regards
Fite

### RE: SOL 200 Problem

The USER FATAL MESSAGES are indicating that your version of nastran does not recognize and support the entries.

For DRESP1, it is saying that the RTYPES: FRMASS and COMP are not recognized and supported.

In regards to TOPVAR, your version of nastran does not recognize TOPVAR as a bulk data entry.

What version of nastran are you using? NX or MSC Nastran? What version/year are you using?

If you are using NX Nastran, FRMASS, COMP and TOPVAR are not supported.

If you are using MSC Nastran, you might be using an outdated version. In that case, you should upgrade to a new version that does supported those entries.

Feel free to email me if you have another nastran sol 200 question. e: christian.aparicio.2000 @gmail.com
