Finite Element Analysis Integration

PASS/START-PROF is now directly integrated with PASS/NOZZLE-FEM Software. It allows to automatically calculate:

  • Stress intensification factors (i) and flexibility factors (k) for all tees, bends, and trunnions in the whole model can be automatically calculated using the finite element method (FEA) on-the-fly.
  • Vessel nozzle and tank nozzle stuffiness, allowable loads, and stresses in the nozzle-shell junction can be calculated using FEA on-the-fly automatically for all nozzles in the model.

PASS/NOZZLE-FEM software is supplied for free to the PASS/START-PROF customers! It means that the price remains $6000-$7800 for a permanent license and much less for 3, 6, and 12-month temporary licenses. A detailed description can be found here

New Capabilities

Added the new MS Word report generator. It has a title page, and contents, and is generated automatically based on the templates, that can be customized. You can insert the logo of your company, change the font, layout, etc.

Added ability to model the internal restraints. Internal restraint allows for example to model the resting support which is connected to another pipe or beam element. It allows taking into account friction, single-directional restraints, and gaps. Also, it allows modeling the pipe connection to the column, and connection to skid, ramp, etc. Example. The pipe lies on the resting support, that is connected to the frame made of I-beams. Between the frame (node 4) and pipe (node 13), we insert a rigid element. On the rigid element at the distance of half pipe diameter, we insert a node 16. In this node, we insert the internal restraint that model resting support.

Internal restraints

Added the new object Beam, a two-node element, that allows modeling the steel or concrete structure, working in the same model with pipes. Beam elements can have different sections: I-beam, Channel, Angle, etc. Profiles can be taken from the beam section database
