can you please tell me how to use mass scaling in hypercrash
Hi,
For mass scaling you can use the Engine-Keyword /DT/NODA/CST, that you can use to scale the timestep and to force a minimum timestep for your calculation.
Either you can enter this manually in the engine file or you can activate the control card in HyperMesh/HyperCrash.
The image attached shows activating the control card in HyperCrash.
/DT/NODA/CST is the formatwhere Tsca is 0.9 Tmin is the Minimum time step user desired to input.
Tsca Tmin
In the engine out file DM/M value in the last column in the RADIOSS Engine listing file will show the total mass added to the model.
For post processing of the added mass, enter the keyword /AIM/NODA/DMAS which gives Nodal mass variation. User can verify the animation files written with this keyword.
Impact Analysis tutorials are available in the RADIOSS help menu.
thank you very much sir
