time step implicit

Altair Forum User

hi,

i am doing a simulation in axisymetric mode, i want to do the simulation for about 200 s, the problem is tha the time step calculated by the solver is too small therefore the simulation would require a huge amont of time, i faced the same problem while simulating a shell however in the implicit solver by changing the nodal time tep i was able to change the time step for the solver, that doesn't seem to work for an axisymetric problem, is there a way to do the same for the axisymetric problem.

thx.

Hi,

Please go through Implicit Time Step in the Help Menu where implicit time step control methods are shown.
