  12 - Cylindrical

  13 - Universal

  14 - Constant velocity

  15 - Planar

  16 - Inline

  17 - Perpendicular

  18 - Parallel axes

  19 - Inplane

  20 - Orient

  21 - Point to Curve

  22 - Curve to Curve

  23 - Point to Deformable Curve

  24 - Point to Deformable Surface

• n1 (Entity) – The object describing the first node entity of the joint element.

• n2 (Entity) – The object describing the second node entity of the joint element.

• orient1_node (Entity) – The first orientation node entity of the joint element.

• orient2_node (Entity) – The second orientation node entity of the joint element.

• orient1_x (double) – x-coordinate defining the first orientation vector.

• orient1_y (double) – y-coordinate defining the first orientation vector.

• orient1_z (double) – z-coordinate defining the first orientation vector.

• orient2_x (double) – x-coordinate defining the second orientation vector.

• orient2_y (double) – y-coordinate defining the second orientation vector.

• orient2_z (double) – z-coordinate defining the second orientation vector.

• set1 (Entity) – The object describing the first entity set used to define the MBD curve.

• set2 (Entity) – The object describing the second entity set used to define the MBD curve.

• typeflag (int) –

  0 - Do not update this joint type.

  1 - Update the joint type.

• nodeflag (int) –

  0 - Do not update the nodes of the joint.

  1 - Update the nodes of the joint.

• orient1flag (int) –

  0 - Do not update.

  1 - Update the first orientation of the joint.

• orient2flag (int) –

  0 - Do not update.

  1 - Update the second orientation of the joint.

• setflag (int) –

  0 - Do not update entity sets.

  1 - Update entity sets used to define the curves.

Example

Update cylindrical type joint elements of ID ‘s 9 and 10 to be joints of type ball
