Package org.jcae.mesh Description

Here is the list of Java environement variables used in the mesher.

Input parameters

org.jcae.mesh.Mesher.mesh1d

If set to true, edge discretization is computed, otherwise it is retrieved from existing files.
Default: true

org.jcae.mesh.Mesher.mesh2d

If set to true, surface discretization is computed, otherwise it is retrieved from existing files.
Default: true

org.jcae.mesh.Mesher.mesh3d

If set to true, assembling of 2D meshes into a final 3D mesh is computed, otherwise it is retrieved from existing files.
Default: true

org.jcae.mesh.Mesher.meshFace

If set to a non-null value, only the face with this index number is meshed. This is useful for debugging purposes.
Default: 0

org.jcae.mesh.Mesher.tolerance

If set to a positive value, boundary nodes which are closer than this value are fused. Warning: This setting is currently disabled.
Default: -1

org.jcae.mesh.Mesher.isotropic

If set to true, 2D meshes are isotropic, otherwise they are anisotropic.
Default: true

org.jcae.mesh.amibe.ds.Mesh.epsilon

Edges smaller than this value are not taken into account. If it is set to zero, all edges are considered even if they are small. If it is set to a negative value, epsilon is computed for each CAD face by taking the maximum between len/100.0 and diag/1000.0, where len is the length criterion and diag the bounding box diagonal length. If epsilon is set to a positive value, this value is used when eliminating small edges.
Default: 0.0

org.jcae.mesh.amibe.ds.Mesh.cumulativeEpsilon

If set to true, edge lengths are cumulated when removing small edges. Thus many small edges can be combined into a meshed edge.
Default: false

Output files

org.jcae.mesh.Mesher.reportFile

If set, this variable contains a file name and a report about mesh parameters will be written into this file. No report is written by default.

org.jcae.mesh.tmpDir.delete

Delete the directory which contains the mesh at the end. Note: UNV file is never deleted.
Default: false

org.jcae.mesh.tmpDir.auto

Ignore the specified tmp dir and create one with File.createTemp
Default: false

org.jcae.mesh.exportMESH

Export 3d mesh in the MESH format.
Default: false

org.jcae.mesh.exportUNV

Export 3d mesh in the UNV format.
Default: false

org.jcae.mesh.exportSTL

Export 3d mesh in the STL format.
Default: false

org.jcae.mesh.exportPOLY

Export 3d mesh in the POLY format.
Default: false

org.jcae.mesh.unv.name

Force the name of the UNV file
Default: <brep base name>.unv

org.jcae.mesh.unv.nogz

If true, UNV file is not gzipped.
Default: false

org.jcae.mesh.Mesher.writeNormals

If set to true, surface normals are written into output files. This can drastically increase output file size, so use with caution.
Default: false

CAD

org.jcae.mesh.cad

This variable can select an alternate CAD engine. As of now, the only supported CAD engine is OCC.
Default: org.jcae.mesh.cad.occ.OCCShapeBuilder

org.jcae.mesh.Mesher.explodeBrep

If set to true, faces are written onto disk, each face into a single BRep file.
Default: false

Visualisation

javax.media.j3d.zFactorAbs

Set polygonOffset for java3d visualisation. See javax.media.j3d.PolygonAttributes javadoc.
Default: 20.0f

javax.media.j3d.zFactorRel

Set polygonOffsetFactor for java3d visualisation. See javax.media.j3d.PolygonAttributes javadoc.
Default: 2.0f

The JVM -ea flag can be used to enable or disable runtime assertions. See Java Runtime documentation.
