Workshop 11 Imprint - Assembly Meshing Wizard

WS11-2 Assembly Meshing Wizard Design goals One comprehensive user interface Intuitive approach for solid pairs specification Mesh seed and Mesh control Surface tri elements Automatic global edge length calculation Additional requirements Check imprint boundaries before meshing Create solid tet mesh individually Check the boundary between meshed solids

WS11-3 Imprint Select All solids to be assembled All solids which should be connected are required to be selected as the first step Select solids to be removed from assemblies Define solid pairs which are not required to be connected Check the imprint boundary If check is ON, boundaries appears after imprint execution

WS11-4 Boundary Check Imprinted boundaries can be seen within transparency solids

WS11-5 Mesh Seed and Mesh Control Mesh seed and Control surface tri-elements can be applied after Imprint

WS11-6 Meshing Select solids to be meshed The target solids should have already been imprinted Select mesh size and priority to solid Mesh size can be defined to each solid Meshing priority can be also defined Define the global edge length This value is applied to the solids with no previously defined mesh size and priority

WS11-7 Mesh Results Congruent meshes are created except the boundary removed from assemblies

WS11-8 Workshops Now try out the following 7 scenarios.

WS11-9 Scenario 1 2 1x1x1 solids w/ congruent faces No gaps No Intersection

WS11-10 Scenario 1 Congruent meshes across boundaries Using Patran 2005 assembly meshing capability

WS11-11 Scenario 2 2 1x1x1 solids w/ congruent faces With Gap of.001 Model global tolerance of.005

WS11-12 Scenario 2 Congruent meshes across boundaries Using Patran 2005 assembly meshing capability

WS11-13 Scenario 3 2 1x1x1 solids w/ congruent faces With intersect of.001 Model global tolerance of.005

WS11-14 Scenario 3 Congruent meshes across boundaries Using Patran 2005 assembly meshing capability

WS11-15 Scenario 4 2 solids w/ non-matching faces Imprint

WS11-16 Scenario 4 Meshing two solids together Using Patran 2005 assembly meshing capability Congruent meshes across boundaries Limitation: Unable to use different mesh densities between solids

WS11-17 Scenario 4 Meshing two solids individually Using different meshing densities Using Patran 2005 assembly meshing capability Non-congruent meshes across boundaries

WS11-18 Scenario 4 Scenario 4a Edit:Solid:Boolean to combine 2 solids Congruent meshes across boundaries Limitation: Unable to use different mesh densities between solids

WS11-19 Scenario 4 Scenario 4b Edit:Solid:Imprint to create matching faces on solid on the left 7 faces now, was 6 Congruent meshes across boundaries Able to change mesh densities across solids

WS11-20 Scenario 5 2 solids w/ non-matching faces Imprint

WS11-21 Scenario 5 Meshing two solids together Using Patran 2005 assembly meshing capability Congruent meshes across boundaries Limitation: Unable to use different mesh densities between solids

WS11-22 Scenario 5 Meshing two solids individually Using different meshing densities Using Patran 2005 assembly meshing capability Non-congruent meshes across boundaries

WS11-23 Scenario 5 Scenario 5a Edit:Solid:Boolean to combine 2 solids Congruent meshes across boundaries Limitation: Unable to use different mesh densities between solids

WS11-24 Scenario 5 Scenario 5b Edit:Solid:Imprint to create matching faces on solid on the left 7 faces now, was 6 Congruent meshes across boundaries Able to change mesh densities across solids

WS11-25 Scenario 6 Multiple solids

WS11-26 Scenario 6 Meshing three solids together Using Patran 2005 assembly meshing capability Congruent meshes across boundaries Limitation: Unable to use different mesh densities between solids

WS11-27 Scenario 6 Scenario 6a Edit:Solid:Imprint to create matching faces on all three solids Congruent meshes across boundaries Able to change mesh densities across solids

WS11-28 Scenario 6 Scenario 6a Limitation: Unable to assembly mesh w/ 2 neighbor solids We plan to enhance Patran assembly meshing to support this scenario

WS11-29 Scenario 7 2 solids w/ edge intersection

WS11-30 Scenario 7 Meshing two solids together Using Patran 2005 assembly meshing capability Congruent meshes across boundaries Limitation: Unable to use different mesh densities between solids

WS11-31 Scenario 7 Meshing two solids individually Using different meshing densities Using Patran 2005 assembly meshing capability Non-congruent meshes across boundaries

WS11-32 Scenario 7 Scenario 7a Edit:Solid:Imprint to create matching faces on solid on the left 9 vertices now, was 8 Congruent meshes across boundaries Able to change mesh densities across solids
