Reducing the frequency at which results are returned can alleviate this problem. Second, since communicating results between the model and XSIM entails significant overhead especially when the model is run on a remote computer, reducing the communication frequency will decrease the time required for a simulation run. Note that in all cases, the model is evaluated at each value of the independent variable determined by its initial value, final value, and increment. Only the frequency at which results are returned to XSIM is altered. Note that for these two options, the results are the exact results calculated by the model.
Linear interpolation is used when required.
If this option is selected but no reference data file is loaded, an error message will be displayed when a simulation run is started and the run will be aborted. The inner and outer loops allow a set of simulations to be run with the values of one or more parameters altered as specified by the user. After the simulation run has completed all the loops, or if the run is cancelled, the parameters changed during the loops are reset to the values they had before the simulation run was started. The name of the parameter to be altered between loops is entered in the parameter field . A parameter name can be entered by typing it, using the paste button, or using a pick control window.
