In the manual it is stated that: &#8220;If constants 1-4 are input and constants 5-8 are omitted, the latter constants default as discussed&#8221;, meaning C9 should be 0.6 which is the default value. However, when I edit the model in APDL C9 is set to zero. What should I do to include in the command the C9=0.6?
