Tutorial B7: Define Properties and Mesh

Create Material

The bracket is made from a stainless steel material. With the iLogic commands, we can specify the complete material definition.

1. Copy the following text:

   strCmdForNewMaterial = "<NewMaterial Name=""16-25-6 Stainless Steel"" ID=""2"" Type=""0"" IdealisationIDList="""" DENS=""8504.9[kg/m^3]"" GE="""" REFT=""[K]"" EX=""19443000000[Pa]"" GXY="""" NUXY=""0.295"" ALPX=""0.00001692[/K]"" SIGXT=""77221000[Pa]"" SIGXC="""" SIGYLD="""" C="""" KX=""25.85[W/m K]"" FailureTheory_Type=""1"" HasConductivityTable=""0"" HasYoungsModulusTable=""0"" NonLinearType=""0"" SN_B="""" SN_Smu=""[Pa]"" SN_N0="""" SN_KF="""" SN_Be="""" SN_Se=""[Pa]"" EN_SF="""" EN_EF="""" EN_B="""" EN_C="""" HasPPFA=""0""/>"

   These commands are equivalent to creating a material through the user interface.

   
2. Paste the text below the existing commands in the Edit Rule dialog.
3. Press the Enter or Return key twice to jump down to a new line.

Create Solid Element Idealization

For this simulation, we’ll apply solid elements to our bracket. To do so, we’ll create a new solid type idealization.

1. Copy the following text:

   strCmdForNewIdealization = "<NewIdealization Name=""Solid 1"" ID=""1"" Type=""2"" AddToFEModel=""1"" Color=""11087083"" CoodinateSystemID=""0"" MaterialID=""2"" EntitiesCount=""0""/>"

   Type = 2 denotes the use of solid elements.

   These commands are equivalent to defining the idealization through the user interface.

   
2. Paste the text below the existing commands in the Edit Rule dialog.
3. Press the Enter or Return key twice to jump down to a new line.

Create Mesh

The mesh is defined using two commands. The <MeshModel> command to define the properties of the mesh and the <GenerateMesh> command to produce the mesh.

1. Copy the following text:

   strCmdForMeshModel = "<MeshModel AnalysisID=""1"" HasContiniousMeshing=""0"" HasMeshTable=""0"" ElementSize=""0.00507369[m]"" Tolerance=""0.000000101474[m]"" ElementOrder=""3"" HasRefinmentRatio=""1"" RefinmentRatio=""0.6"" MinTriangleAngle=""0.349066[rad]"" MaxTriangleAngle=""0.523599[rad]"" MaxElementGrowthRate=""1.5"" SuppressShortFeature=""0.02"" MinFeatureAngle=""0.0349066[rad]"" HasProjectMidsideNodes=""0""/>"
   
   strCmdForMesh = "<GenerateMesh/>"

   Element Order = 3 denotes the use of parabolic elements.

   These commands are equivalent to defining the mesh properties through the user interface.

   
2. Paste the text below the existing commands in the Edit Rule dialog.
3. Press the Enter or Return key twice to jump down to a new line.
