Structural and aerodynamic data transformation using inverse isoparametric mapping
Abstract
The inverse isoparametric mapping is presently used to transform such state variables as displacement, load, stress, pressure, temperature, etc., from structural grid points to aerodynamic grid points. The wing plane's form can be represented by either fournode or eightnode isoparametric finite elements. Extrapolation to the case of control surfaces becomes possible via combination of wellknown extrapolation techniques and the inversemapping procedure.
