I am still trying to create a rigid body but I found this problem:
First of all I defined a node:
[COLOR=red]*NODE,NSET=ROAD
1111, 0.0, 0.0, -42.2[/COLOR]
And then a rigid body. As reference node I can only insert the number and not the name otherwise It will be a mistake but also in this case it become an error:
[COLOR=Red][I][I][I]*RIGID BODY,REF NODE=1111,ANALYTICAL SURFACE=SROAD
The error is the following one:
***ERROR: PARAMETER REFNODE MUST HAVE A VALUE
LINE IMAGE: *rigidbody, refnode, analyticalsurface=Assembly-1_SROAD
***NOTE: DUE TO AN INPUT ERROR THE ANALYSIS PRE-PROCESSOR HAS BEEN UNABLE TO
INTERPRET SOME DATA. SUBSEQUENT ERRORS MAY BE CAUSED BY THIS OMISSION
*rigidbody, refnode, analyticalsurface=Assembly-1_SROAD
*contactpair, interaction=SRIGID
*surface, type=CYLINDER, name=Assembly-1_PART-1-1_SROAD
***ERROR: PARAMETER REFNODE MUST HAVE A VALUE

***ERROR: THE ANALYTICAL SURFACE ASSEMBLY-1_PART-1-1_SROAD IS MISSING THE
ASSOCIATED *RIGID BODY OPTION
THE PROGRAM HAS DISCOVERED 5 FATAL ERRORS
** EXECUTION IS TERMINATED **[/I][/I][/I][/COLOR]
I don t understand:
1) What the error means
2) why it is repeted
Hope someone can help me.
Thats strange. Your rigid body command looks OK to me.
Are you sure your inp-file contains that exact command?
