The customer tries to create a Mesh in Solid Edge Simulation.
Solid Edge then appears to need some time to figure out what to do but ultimately no Mesh window is shown.
After changing the default printer in Windows, Solid Edge will then process and the Mesh window is shown as expected.
In Windows open 'Printer & Scanners'.
Toggle the setting 'Let windows manage my default printer' - if it ON turn it OFF and vice versa.
This is a rare fault, but changing the setting should solve the Mesh problem.
