What does the message "Non-Zero Surface Integral" mean and how do I solve this problem?

After the command Check Data has been invoked, EASE calculates the sum of all faces areas. This sum can be considered as a three-dimensional value because every area is added dependent on its orientation in the room. For example two parallel faces with equal areas looking at each other would give zero.
As a result the surface integral of a closed room must also equal zero with a little tolerance.

To solve this problem: In most cases there are two or more faces in the same location. Delete one of them.

Slow Project Data Module

I have finished now a project with approximately 300 Faces and 40 Loudspeakers. But anytime I change something the Project Data Window takes several seconds up to a minute to update the view. Is this a bug?

No, propably not. There are two main reasons for the editing module slowing down that dramatically.

Reinstall Room symmetry

Q: After I completed my project on a symmetrical base I had to modify it again. I released the symmetry to allow the new data to be entered. As a result of the calculations I found it necessary to include some more symmetrical walls. So I reinstalled the symmetry. My problem is, all of the faces and other items seem to appear twice. Is this a program bug?

What is Ease Room?

Help on Ease Room - Edit Project Data / Case Data / Cluster Data

Ease Room is a module of EASE 4.0/3.0 that allows you to insert and modify buildings (eg. rooms, studios, stadiums), loudspeaker cases, loudspeaker clusters, furniture (like chairs, tables) and room parts (like columns, balconys, windows) in a wireframe view.
As a basic module of Ease it is used in many different ways:

How do I fix “Face Mismatch or Hole in Room”

After clicking Check Data [F5], or attempting to Save Project Data [F6], I receive the following message:

"Face Mismatch or Hole in Room.
Use Check Holes to get detailed information."

What does this mean and how do I solve this problem?

This is a sign that your room model has geometry problems, the so-called “holes”. Holes are the result of violating one or more conventions of EASE and they need to be fixed before you can go on and perform simulations.

I am trying to save/open an EASE project on my network and get "Run-time error '75', Path/File access error". How do I fix this problem?

This error is the result of trying to save an EASE project to a network location that contains a double backslash ("\\") in the path name. To avoid the problem, please use "Map network drive" in Windows Explorer to first map the desired network folder as a hard drive on the local computer. The EASE project can then be saved to or opened from the mapped hard drive on the local computer.
