This page contains a record of various issues we've run into while using NX. They've been documented here for future reference.

Problem: I've opened NX and I receive the following message:

Solution: You're probably not connected to the UTAT VPN. Go to OpenVPN and connect to the UTAT VPN, then open NX.

Problem: I've set up my simulation and hit Solve, but the results don't appear. A text document is generated, the bottom of which looks like the following:

Solution: If you haven't run a simulation since our most recent NX license renewal, it's possible that this error arose due to the license being renewed. To fix this, uninstall NX by going to Start > Siemens NX > right-click on NX > Windows Programs and Features > right-click on Siemens NX > Uninstall. Wait for Windows to finish uninstalling NX. Once NX is uninstalled, follow the steps in this doc to reinstall NX on your computer. Once NX has been reinstalled, you should be able to run your simulations.

Problem: I want to perform an analysis quality check after the simulation is complete, but when I click on Check Analysis Quality in the Analysis Job Monitor window, I receive the following error message:

Solution: Expand the Solution drop-down list and right-click on whichever subcase is applicable to your simulation (e.g., for a modal analysis, you would right-click on Subcase - Dynamics). Next, click Edit, then select the wrench icon next to Output Requests. Scroll through the menu and click on Strain, then check Enable STRAIN Request. Click Okay twice and you should be good to go.

You should receive an output that looks like the following (with different numbers, of course):

Problem: I've performed a modal analysis and my total effective masses for all axes isn't greater than 90%.

Solutions: There may be many reasons why you're getting these results. Here are some suggestions you can try:

1. Simulate more modes. As you increase the number of modes, your total effective mass for all axes should go up.

Problem: I receive an error message saying "Error: Assembly node or element label conflicts exist" when attempting to run a simulation.

Solution: When you create a .afm file, each .fem file you insert into it will have its own set of element and node labels, so when you combine them in the .fem file there will be multiple instances of a given element label (since all label numberings begin at 1 in each .fem file). To reset the labels in your .afm file, go into your .afm filed right-click on your file name at the top of the Simulation Navigator, then go to Assembly Checks > Assembly Label Manager. Click on Automatically Resolve and you'll see green check marks appear in the "Status" column in the "Labels" table.

Problem: Part of my model appears to have disappeared and different parts of my model become visible as I rotate it around.

Solution: NX is conserving the amount of graphics that it has to display. To fix this, right-click anywhere in the background of the model viewing area and select Fit.

Problem: I have shells that appear transparent.
