ASPECT RATIO CHECK

 

This function allows the user to check the aspect ratio of the displayed plate and solid elements. The aspect ratio is the ratio of the longest side to the shortest side of an element. In eta/DYNAFORM, the default aspect ratio is 8.0 to 1.0. The user may adjust it as necessary.

 

1.        The user may accept the default value of 8.0 or enter any positive real number that is a valid value for the aspect ratio. eta/DYNAFORM runs a check on the values for the aspect ratio. Any elements that exceed the defined aspect ratio are highlighted. The messages echoed in the PROMPT window are:

 

xxx ELEMENTS FAILED CHECK  ASPECT RATIO= xxx

      or

              ALL ELEMENTS PASS CHECK

 

The number of failed elements and maximum aspect ratio will be displayed in the PROMPT window.

 

2.        If there are failed elements, a DYNAFORM QUESTION window appears.  See Figure 5.6.4.

3.        eta/DYNAFORM prompts:

 

                 SELECT ELEMENT FOR ASPECT RATIO

 

The user can select any highlighted element, and its aspect ratio will be shown in

the PROMPT window.
