<p>Hi Simon,</p>
<p>There has been a bug in Karamba3D 1.3.1: The BESO weights for truss elements were calculated incorrectly.</p>
<p>The problem is solved in the current build of Karamba3D 1.3.2.</p>
<p>Best,</p>

<p>The model attached in my previous message was the smallest definition I could do showing the bug clearly. The module functions normally under other conditions. <br/><br/>I'm using Build 0.9.0076 Student version.</p>

<p>Hello Simon,</p>
<p>this is still on my TODO list. <br/>Do you have a small definition which I could use for debugging?</p>
<p>Which version of Karamba3D do you use?</p>

<p>Hi Simon,</p>
<p>the algorithm should be deterministic. If not it is a bug.</p>
<p>I will take a look at it - it may however take some time since I am away from office for a few days.</p>
