CFVR5231 - Prestressing tendon definition from lines, without a support beam.
Solid model tendon analysis using free tendon capability ~GENTEN command.
A prestressed solid beam with rectangular section which dimensions are 0.4x0.3m and 8m of length, a table of total additional losses is applied. This test checks that final applied cable tension is equal to initial tension minus total losses at each point.
The final array must give null results for all its components.
