Hi Good Afternoon to all,

                                          I have two doubts in Abaqus CAE modeling, please share your valuable information regarding this.

1) Am building a 3 D frame structure in which i have 3 part instances beam1, beam2 & beam3. I have assembled them just like in image 1, now my doubt is how many connection builders i have to create between these 3 instances. i have done like this  ConnectBuldr1 between Beam1 & Beam2

        ConnectBuldr2 between Beam1 & Beam3

      ConnectBuldr3 between Beam2 & beam 3.............whether its correct? if not how many?

2) How to apply a point mass in the center of a circular cut out?

   I know to create a plate with circular cut out.

 How to create a rigid elements to connect point mass to circular cut out just like below image, in which module of Abaqus CAE i ll get this option to create and in which module of Abaqus CAE i can put point mass in center? Thanking you all in advance
