pentas in a stressed area

I am running a simple rotation analysis(RFORCE). I have penta elements in a highly stressed area is it a problem ?

Does it gives wrong stresses.

The below results are for very coarse mesh .

After finding the highly stressed regions, i refined the mesh which caused pentas in that region as in the picture.

Do you're speaking about surface or solid mesh?

solid mesh ....i did 2D and made it 3D->Drag.

I circled area is to be studied (stresses are high in this region )

You got high stress level, because your structure, your load. Penta elements are also as good as another element type.

At your place, I'll check this high stress value to see if it's a physical value? or a numerical value?

thanks for the reply very useful point.

How do you know its a physical value or numerical , is it by comparing test results ?
