Bug of bend component - peipei - 28-08-2012

Hi, everyone,

Recently I find a strange situation in my model.

The bend radius of one component which in the input table of "POLYDIF" is 1981.2mm. However, this bend radius is 0 in the output table "SHAPEP". See component 25VB2.

Is there anyone ever had this problem?

Regards

Hi peipei,

I checked your issue with a colleague. The Radius is set to 0 in SHAPEP because the calculated bend length becomes less then 0.2 times the specified bend element length (in POLYDIF). In your case the bend length is approximately 8 [mm] whilst the specified bend element length is 50 [mm].

If I am correct you should have got warning W200/4: "Zero bend angle with radius". Unfortunately this is not a very proper warning for this situation since the bend angle is not near zero, but the calculated element length is too small. The warning will be either adapted or a new warning will be added to notify the user that the Radius is set to 0 due to a bend length less then 0.2 times the specified bend element length. This issue is noted as ticket J-335.

Hi, Herwig,

Thanks for the reply. What is your suggestion in this case?

Hi peipei,

If you are sure that you want this very small bend, reduce the bend element length for 25BV2 in the POLYDIF table (a lenght of 30 [mm] should do). This change might require you to reduce the length of adjacent elements as well.

This warning description was extended in version 4.2.2.
