Have you been successful with the CZM with a very small model of 2 bricks and one layer of mortar?

Did you know you can make the same setting to many contacts at once?

In Mechanical, when you have 400 contacts, click on the first contact in the Outline, scroll to the last contact in the Outline, hold down the Shift key and click on the last contact thereby selecting all 400 contacts. Then in the Detail window for the Contact, setting them all to CZM at once.
