Applying transient initial velocity condition to nodes.

Creator

Good day,

I'm a newbie to FEMAP from MSC Products (Patran, Dytran, Mark).

I would like to subject certain nodes of my model to initial velocity condition but not sure how to set this up in FEMAP.

Create a new load case that specifies the initial velocity for the nodes desired.

 

Then in the Analysis Manager, select this new load case in the field labeled Initial conditions.

 

So you have 2 load cases defined; one for the initial conditions and a second with your transient excitation defined.

 

If you do a preview input you will see the following:

 

CEND
TITLE = Direct Transient
ECHO = NONE
DISPLACEMENT(SORT1,PLOT) = ALL
ACCELERATION(SORT1,PLOT) = ALL
SPCFORCE(SORT1,PLOT) = ALL
SPC = 1
DLOAD = 1
TSTEP = 1
IC = 1

 

and in the bulk data you should see:

TIC 1 1 1 .1
TIC 1 2 1 .1
TIC 1 3 1 .1
