DBuild命令通过集合对象建立有限元模型。
|
用法要点：
1. 由网格面构成的封闭空间将被生成为实体单元；
2. 对点、折线、网格面的用户属性文本添加“Group”键并设置其值即可实现对其分组；
3. 对网格面的用户属性文本添加“Type”键并将其值设置为“FaceElement”则可生成面单元；
4. 对折线的用户属性文本添加“Type”键并将其值设置为“LineElement”则可生成线单元；
5. 对点的用户属性文本添加“Type”键并将其值设置为“PointElement”则可生成点单元。
Usage Tips:
1. closed space enclosed by meshes will be generated as solid elements;
2. in the User Attribute Text, add keys named as "Group" and set the corresponding values to points, polylines, and meshes can achieve their classification;
3. in the User Attribute Text, aadd keys named as "Type" and set the values equals "FaceElement" to the meshes can generate face elements;
4. in the User Attribute Text, aadd keys named as "Type" and set the values equals "LineElement" to the polylines can generate line elements;
5. in the User Attribute Text, aadd keys named as "Type" and set the values equals "PointElement" to the polylines can generate point elements.
DBuild命令通过点、多段线和网格来生成有限元模型，其支持ABAQUS、ANSYS、FLAC3D、NASTRAN、MIDAS、VTK、CSV等。封闭网格将被转化为实体单元并分组。开放网格将被转化为面单元如果其被赋予了FaceElement类型。多段线将被转化为线单元如果其被赋予了LineElement类型。点将被转化为点单元如果其被赋予了PointElement类型。您可以使用关键字Group来对对应对象进行分组。
The DBuild command builds the finite element model through points, ploylines and meshes, which supports ABAQUS, ANSYS, FLAC3D, NASTRAN, MIDAS, VTK, CSV, etc. Closed meshes will be transfered into solid elements and grouped. Open mehses will be transfered into face elements if their Type were assgined to be FaceElement. Polylines will be transfered into line elements if their Type were assgined to be LineElement. Points will be transfered into point elements if their Type were assgined to be PointElement. You can use keyword Group to group the corresponding objects.
本命令有如下参数：
ElementShape - 实体单元形状，其可为Tetrahezdron或Mixed（其为四面体、金字塔体、楔形体及六面体的组合）；
ModelParttern - 有限元模型规则，其可为Unstructured或Structured；
ShapeQuality - 有限元模型质量；
MaxGradation - 网格面中边长度的最大比值；
RunningSpeed - 网格重划分运行速度，速度越慢网格质量越高；
IgnoredObjectsByVolumeMesher - 是否显示被体积网格生成器忽略的对象，其中Hide = 不显示，Show = 显示；
ModelName - 有限元模型名字；
OutputDirectory - 输出文件路径；
OutputFormat -有限元模型格式。
The command has the following input parameters:
ElementShape - the shape of the solid elements, which can be Tetrahezdron or Mixed (i.e., a combination of tetrahezdron, pyramids, wedges, and hexahedrons);
ModelParttern - the parttern of the finite element model, which can be Unstructured or Structured;
ShapeQuality - the quality of finite element model;
MaxGradation - the max ratio between the edges of a mesh face;
RunningSpeed - the speed of the remesh process, the slower speed corresponds the higher quality;
IgnoredObjectsByVolumeMesher - whether to show the objects ignored by the volume meshes, where Hide = not show, Show = show;
ModelName - the name of the finite element model;
OutputDirectory - the directory of the output files;
OutputFormat - the formats of the finite element models;
