If a mesh needs to be rotated, select Rotate Mesh from the pull-down menu and click Edit… to open the Rotate Mesh dialog.

Enter the Euler Angles Phi, Theta, Psi by which the selected mesh should rotate. More details about Euler Angles can be found in the GadGeo chapter. The rotation can be around the chosen Center of Rotation. See the explanations about Set to Domain Center, Set to Domain Origin, and Set to Center of Mass.

An example of mesh rotation is shown below. The image on the left shows the original mesh of the match structure. The image in the middle shows mesh after the rotation of Phi with 90° around the Domain Origin, and the right image shows the rotation of Phi with 90° around the Domain Center.
