Hello All,

i have the following warning message displayed for an explicit simulation. What could be the reason for this warning?

I am using amplitude to define the displacement of "Welle" in step 2 and then the "Welle" is not moving in step 3.

***WARNING: The option *BOUNDARY,TYPE=DISPLACEMENT has been used with a jump

of 1.80000 at DOF 2 of node WELLE-1.1 at the beginning of step 3.

***NOTE: Displacement boundary conditions with prescribed jumps will be

enforced as defined, minus the value of the jump. The jumps might be

caused by:

1) A discontinuous *BOUNDARY, TYPE=DISPLACEMENT definition.

2) Initial contact adjustments at the beginning of the first

step.

3) Locating the rigid body reference node with the POSITION=CENTER

OF MASS parameter.

4) Use of an amplitude curve to prescribe the boundary conditions

in an analysis with a large number of increments; precision

error may cause a small drift from the prescribed displacement.
