Problems using logical expressions for "partly-coloured plot"

Please login with a confirmed email address before reporting spam

Hi,

currently I try to deal with a "partly coloured plot" using the element selection mode, located in the general plot parameters.

I already studied the manual where an example for a logical expression is listed. Unfortunately COMSOL replies with an Syntax Error when I try to realize this example.

My intention is to plot a 2D Model where only a part is shown coloured.

For example: 0.1 < x < 0.3 and -0.1 < y < 0.1.

I also studied the logical expressions list in the users manual, without success.

An example:

In my case, plotting the logical expression "x > 0.1" works fine however the expression "x > 0.1 & y > 0.1" replies an error.

Anyone who could help me solving my problem?

Problem solved!

For plotting an coloured area for example: 0.1 < x < 0.3 and 0.1 < y < 0.3 the correct logical expression is as follwed:

x > 0.1 && x < 0.3 && y > 0.1 && y < 0.3
