Hi,

In most cases, it refers to some faults on the elements with different colour especially when the elements were chosen randomly.

If you put the mouse on them you will get more information about each colour.

Sometimes, you need to press on the elements with different colour to see the required information.

Good luck.

Thanks Dr. Ahmed

faults like what Dr.?

meshing?

the slab and parapet are both modeled as shell elements. when i view them as shell elements they show these two color.

but when i go to plot control -> style -> size and shape -> display element ON,, i get no colors. only blue one as attached below. Ahmed Mahmood Abdullah Daabo

Yes of course, chosen element type is not fitted with that specific section (with different colour) in geometry.

The idea behind the sizing is to reduce the element size, in order to cover all the geometry .

By doing this, you succeed in making all the geometry meshed, however, you increased the number of elements which will increase the computational cost and at the same time affect the solution accuracy.

You can compare the two methods to see the difference in the element number after meshing the geometry.

Good luck
