Defining Materials and Media Types

Materials can be defined in CUBIT and assigned to element blocks. If an element block is exported without a material assigned to it, a default material (with properties for common steel) will be exported for it.

Create Material [id] [Name <'name'>] [Elastic_modulus <value>] [Poisson_ratio <value>] [Shear_modulus <value>] [Density <value>] [Specific_heat <value>] [Conductivity <value>] [User constants <value ...>] [DepVar <value>]

Modify Material <id_list|'name'|all> [Name <'name'>] [Elastic_modulus <value>] [Poisson_ratio <value>] [Shear_modulus <value>] [Density <value>] [Specific_heat <value>] [Conductivity <value>] [User constants <value ...>] [DepVar <value>]

Create Media [id] [Name <'name'>] [Fluid|Porous|Solid]

Modify Media <id_list|'name'|all> [Name <'name'>] [Fluid|Porous|Solid]

Materials can be created with any number of the following material properties:

• Elastic modulus
• Poisson Ratio
• Density
• Specific Heat
• Conductivity
• Shear Modulus (must satisfy E = 2G(1+v) )
• User Constants
• DepVar (Only written to Abaqus file)

Media types include:

• Fluid
• Porous
• Solid

Any properties that are not initialized by the user will have a default value of 0.

Materials and media types can be listed and deleted using the following commands:

List Material <id_list|'name'|all>

Delete material <id_list|'name'|all>

List Media <id_list|'name'|all>

Delete Media <id_list|'name'|all>

Materials and media can be added to an existing block using the following command:

Block <id> Material <id|'name'>

Block <id> Media <id|'name'>
