Export - FEA Loads

File → Export → FEA Loads             Shared Dialog Box
Export FEA load information.
Before exporting FEA load information, you must run a Simulation of your model.
Learn about:
 
For the option:
Do the following:
File Type
Set to FEA Loads.
File Format
Select the file format for the loads file that you want Adams View to create.
Inertia
Clear the selection of this option if you would like to output external loads only.
■When selected, Adams View outputs inertia loads in addition to external loads. Inertia loads include linear acceleration, angular acceleration, and angular velocity of the part or flexible body. Reaction loads include applied and reaction forces acting on the body.
■When cleared, Adams View specifies a load imbalance for the body, and you must employ a technique, such as inertia relief in the finite element program, to recover the inertia loads based on external loads.
File Name
Enter the name of the file to be created. If you want the file written to a directory other than the one from which you are running Adams View, enter the path name in the File Name text box.
Analysis
Enter the simulation containing the information you want to export.
Loads on Rigid Body/
Loads on Flexible Body
Select whether the body whose load information you want to export is a rigid or flexible body.
Rigid Body FEA origin marker
For a rigid body only, enter the marker to which all load information will be relative. The marker location and orientation must correspond to the origin of the part in the FEA program.
Flexible Body Name
For a flexible body only, enter the name of the flexible body. Adams View assumes that its FEA origin is the same as it was when the flexible body was defined.
You can skip the next two options in the following cases:
■For flexible bodies because the node IDs at each load location are known.
■For rigid bodies if the node IDs are not available. Then, the FEA input file will contain the locations (with respect to the FEA coordinate reference) and Adams ID label of the marker at each load location. You will need to edit the file, however, replacing these labels with the actual node IDs, once they are known.
Add Load Points to Nodes Table
Select to have Adams View calculate the points on the part where forces are applied.
Adams View calculates the load points and places the points and their locations in the Nodes table of the File Export dialog box. The node coordinates are displayed relative to the FEA origin of the rigid or flexible body. You might need to resize the File Export dialog box to see all the point locations. See Example of Nodes Table.
Node_id/Scan file for IDs
For rigid bodies only, assign node IDs to the load points Adams View found, if desired. You can do one of the following:
■Type in the node IDs in the Node Id column fields.
■Select Scan file for IDs to have Adams View read in a text file containing the node IDs. For more information using a text file, see Process for Exporting FEA Loads.
Because the loads file is a text file, you can always add the node IDs to the file as you add the load case to your FEA dataset.
Note: For flexible bodies, Adams View automatically assigns node IDs to the load points based on the actual node IDs of the flexible body at these load locations.
Output at times
Do one of the following depending on the load information you want Adams View to export:
■To generate a complete loads history, leave the Output at times text box blank. Adams View exports load information at every output step in the simulation. This is the default setting.
■To generate only load information for certain output times, enter the desired output times, separated by commas (,) in the Output at times text box. Adams View exports a single load case at the time closest to the requested time.
For ABAQUS, ANSYS, and NASTRAN, you can also enter a tolerance (+ or - a value) for the output times. For example, if you requested output at time steps 2 and 5 with a tolerance of 0.1, Adams View generates a load case for all output steps between 1.9 and 2.1 and 4.9 and 5.1.
For DAC and RPC III, you can enter a start output time and an end output time.
 
Caution:  
Note that loads are output in the Adams View modeling units. These units must be consistent with those specified in the finite element model or the results of the FE analysis that includes the Adams loads will be incorrect. After completing the Export FEA Loads dialog box, Adams View displays the current modeling units and gives you a chance to modify them before continuing with the FEA loads export.
