The Part Replacement utility enables you to replace elements in an existing component/part (PSHELL) with new elements. The utility also restores the referenced items in the original model to the new part, e.g. 1-D connections, masses, equations, boundary conditions, and loads. A message log is provided which lists the entities being replaced and reconnected as well as cases that require, or will require, user interaction. The Part Replacement utility generates a log file that contains a list of the entities being replaced and reconnected in addition to cases that require user interaction.
To replace elements in parts using the Part Replacement utility:
In the Old part: field, select a component by clicking the button, which opens a comps selector in the HyperMesh main menu area. Choose a component and click proceed. The new part is created in the HyperMesh database.
If you already created a new part in HyperMesh, delete it before performing this step.
In the New part field, select a part (sub-model) to be imported into HyperMesh and click import.
(optional) Clear the Delete old part check box to save the old part at the end of the replacement procedure.
(optional) Click View log… at any time to open the Part Replacement utility’s log file.
Click Next.
The following dialog appears:
In the New part field, select a component by clicking the button, which opens a comps selector in the HyperMesh main menu area.
Choose a component, click select and click proceed.
Click Next.
The following dialog appears:
(optional) Select a material for the new part from the radio button list of available materials that appears in the dialog and click Apply. The following dialog appears:
Specify a tolerance value for the Fix 1-D connections/meshless welds option. This option provides an automatic and an interactive reconnection to the new part for 1-D elements (beams, rigids, springs, etc.) and meshless welds (beam type 9 and hexa). The tolerance value determines the range of 1-D connections and meshless welds that will be replaced. Elements that cannot be replaced will be displayed in red.
Click Apply.
If there are problems with the reconnections, the results are displayed in tabs on the dialog, as shown here
Click the EID field on the 1-D tab to select the remaining elements, increase the tolerance, and preview the effect of the increased value on the 1-D elements.
Click Apply to use the defined tolerance to fix the elements displayed with a green status.
A message appears that reports the tolerance used to fix the selected elements. If some elements still report as failed, repeat step 12 using a higher tolerance value.
Repeat this process for the Meshless welds tab.
Masses attached to the old part can be connected to a new part using the basic steps outlined above. In addition, HyperMesh can detect and fix the following individual loads: forces, moments, temperatures, equations, and constraints. Pressure must be corrected manually.
