[FAQ]

Why am I getting this error when I try to make a mesh in Turbogrid: ERROR U Param must be between [0.0, 1.0]. Input: 1.00017 I am not sure what this parameter is, what can I do to get around this? This error occurs when the hub and/or shroud surfaces sit just inside the blade leading and trailing edges instead of extending beyond them. The remedy is to extend the hub and shroud surfaces so that they extend past the leading and trailing edges of the blade. On rare occasions, the U Param error can occur when the profile.curve file has leading and trailing edge notations reversed. The can happen if the profile.curve files are being edited outside of BladeModeler.
