Summary:PURPOSE:To make technical knowledge unnecessary by evaluating statistically a relative error based on the calculated result of reference mesh number for the number of meshes of the deviation of the calculated result obtained by an automatic mesh control arithmetic part. CONSTITUTION:The automatic mesh control arithmetic part 1 extracts data related to the number of meshes from among input data, deletes a every second mode on the boundary and forms several kinds of corresponding mesh data, and executes a numerical value calculation program by using each mesh data, and outputs results to several pieces of result output files 11 to 14. Next, an error statistical information arithmetic part 2 calculates the average and the variance of the relative error between each result output data of the results obtained by changing the number of meshes and reference data on the basis of the result output data of the calculated result output file 11 corresponding to the maximum number of meshes. Error statistical information obtained in this way is outputted by an error statistical information output part 3 by a diagram to make the information of the error easy to see. Thus, the technical knowledge becomes unnecessary.
