Contacts Panel - Properties Tab - Point to Deformable Surface Contact |
From the Point to Deformable Surface Contact -Properties tab on the Contacts panel, you can define the contact method and the properties for the option type selected.
Select: |
To: |
---|---|
LINEAR |
Select this type of contact algorithm to model the contact force using stiffness and damping values. |
POISSON |
Select this type of contact algorithm to model the contact force using the penalty method. |
User Defined |
Select this type of contact algorithm to model the contact force using the user defined method. |
Flip normal |
For a 3-D object, the normals point outward which represents a typical outer surface of a volume. Flip normal can be used to turn that surface into a void, or "hole". |

Use: |
To: |
---|---|
Radius |
Enter the radius of the sphere that the deformable surface will be contacting. |
Stiffness |
Enter the stiffness of the contact force that applies to the Linear contact method. |
Damping |
Enter the damping of the contact force that applies to the Linear contact method. |

Radius |
Enter the radius of the sphere that the deformable surface will be contacting. |
Penalty |
Enter the penalty value to model the contact force with the Poisson method. |
Restitution |
Enter the value representing the energy loss for the Poisson method. |

Radius |
Enter the radius of the sphere that the deformable surface will be contacting. |
||||||
User expr |
Provide an expression with the USER solver function with parameters being passed to the user subroutine. |
||||||
Use local file and function name |
Activate the check box to specify a local file where the subroutine code can be accessed by the solver. The type of file to be specified will depend on the selected Function Type. For example if DLL/SO is selected, you can specify a file with a .dll extension (for Windows) or an .so extension (for Linux). |

Function Type |
Valid options for MotionSolve:
|
||||||
Function Name |
Specify the function name in the sub-routine that is used to calculate the contact force. MotionView provides PTDSFSUB as the default, which is the default function used by MotionSolve. |
