Isotropic

1. The first method of creating an isotropic material is:

   1. Click Materials within the Definitions section under the EMA3D tab in the ribbon.

   

   2. Click the material type in the drop-down list.

   3. To use a predefined material: In the Properties panel select the Material Library. A new window will appear. In the pop-up window, select the Library or another material database to find a predefined material. Double click to view and change the new material's properties. Or move to the next step to create a custom material. All custom materials will be stored in the Material Library.

   

   4. Click General to view and change any property values. The adjustable properties are defined in the table at the end of this section. The color is in A, R, G, B format and choosing an A between 0 (most transparent) and 255 (opaque) can make the color and mesh semi-transparent.

   

   5. Click on the appropriate selection tool (i.e., body , surface , or line ) tool in the top left of the model window to restrict the assignment definition.

   6. To assign material properties, either select the geometric entity in the model window or in the Structure Tree.

   

   7. The selected surfaces will be recolored in the model window.

   

   8. To hide the color and revert to the original, more transparent view, click the eye next to the material type under the Definitions node in the Simulation Tree to hide specific materials.

   

   9. Repeat the above steps to assign as many materials as desired.

   10. Users can edit material properties by following the steps above to return to the material''s Properties Panel or by right clicking the material name in the Simulation Tree and selecting Edit Assignments.

   

   11. Click to complete the material assignments.

2. This method does not open the material properties panel nor does it allow the user to multiple geometric entities in the model window. Rather, this method is a faster way to assign a previously-defined material to a selected entity in the model window or in the structure tree. Though it is not strictly required for the user to define a material using method 1 prior to using method 2, but the recommended workflow is to define materials and make initial assignments using method 1 and then, if desired, use method 2 to quickly make later assignments.

   1. In the model window right click on the geometry to which to assign a material.

   

   2. Alternatively, in the structure tree, right click on the geometry to which to assign a material.

   

   3. In the pop-up menu select the type of material assignment (i.e. body, surface, line - only applicable options will be displayed).

   4. In the second pop-up menu, select the type of material (e.g., isotropic).

   

   5. A new window will appear select the desired material name. Note that only previously-defined materials will appear in the Local or Library tabs which is why this method is recommended only after materials have been defined.

   

   6. The selected geometry will be immediately recolored in the model window indicating that the material was successfully assigned. There is no farther option to select more entities as in method 1 - users will have to follow the steps in method 2 again to assign more materials.
