A display shows, in response to the repeated operation by the operation device, the calculated physical behavior obtained by the operation device for each predetermined unit of change in the physical quantity. A temporary stop device temporarily stops the operation by the operation device. A condition altering device alters operation conditions in a temporarily stopped state effected by the temporary stop device. An operation restarting device restarts the operation by the operation device based on the operation conditions altered by the condition altering device after the operation is temporarily stopped by the temporary stop device. ## Claims ### Claim 1 An operation tracking system comprising: an operation means for repeating an operation for calculating a physical behavior, which corresponds to a certain change in a physical quantity of a predetermined model, for each predetermined unit of change in said physical quantity; an operation control means for controlling the operation performed by said operation means; and a display means for displaying, in response to the repeated operation by said operation means, the calculated physical behavior obtained by said operation means for each predetermined unit of change in said physical quantity; said operation means completing one set of analysis after performing a predetermined number of repeating steps of operation which has been set beforehand, said operation control means comprising: an analysis execution means for setting one or a plurality of steps as said predetermined number of steps so as to perform an operation analysis by said operation means; an operation condition setting means for setting, each time the operation analysis is completed by said analysis execution means, operation conditions for a next analysis based on results of thus completed analysis; an operation continuing means for making said analysis execution means continuously perform the operation analysis using thus set operation conditions; a temporary stop means for temporarily stopping the continuation of the operation by said operation continuing means; a condition altering means for altering said operation conditions for said operation under a state temporarily stopped by said temporary stop means; and an operation restarting means for making said operation continuing means restart the operation analysis based on the operation conditions altered by said condition altering means after said operation is temporarily stopped by said temporary stop means. ### Claim 2 (depends on 1) An operation tracking system according to claim 1, wherein said operating means uses a general program by which a repeated calculation is performed so as to effect the analysis, while, each time one or a plurality of sets of the repeated calculation by said general program are effected, said operation condition setting means sets the operation condition for renewal and Judges whether there is a temporary stop instruction from said temporary stop means or not, thereby making said operation continuing means continue the operation when there is no temporary stop instruction. ### Claim 3 (depends on 1) An operation tracking system according to claim 1, wherein said operation control means has a signal input means, while transmission of a temporary stop signal for temporarily stopping said operation from said temporary stop means, transmission of a condition altering signal for altering the operation conditions from said operation altering means, and transmission of an operation restarting signal for restarting the operation from said operation restarting means are effected by said signal input means. ### Claim 4 (depends on 3) An operation tracking system according to claim 3, wherein said signal input means comprises a keyboard. ### Claim 5 (depends on 3) An operation tracking system according to claim 3, wherein said display means displays, during the time when said operating device performs the operation, the physical behavior of said predetermined model corresponding to results of the operation and a button for inputting said temporary stop signal, while displaying, during the time when said operation is temporarily stopped, the physical behavior of said predetermined model corresponding to results of the operation at the time when said operation is temporarily stopped and a screen for altering the operation conditions. ### Claim 6 (depends on 1) An operation tracking system according to claim 1, further comprising a step-back means for attaining results of said repeated operation traced back by an arbitrary number of steps when temporarily stopped by said temporary stop means, said operation restarting means making said operation continuing means restart the operation analysis from an operation state traced back by said arbitrary number of steps based on the operation conditions altered by said condition altering means. ### Claim 7 A method for calculating a physical behavior by using an operation system which comprises an operation means for calculating said physical behavior, which corresponds to a certain change in a physical quantity of a predetermined model, for each predetermined unit of change in said physical quantity; an operation control means for controlling the operation performed by said operation means; and a display means for displaying, in response to the repeated operation by said operation means, the calculated physical behavior obtained by said operation means for each predetermined unit of change in said physical behavior, said method comprising the steps of: a first step for setting one or a plurality of repeating operation steps as number of operation steps for a single operation analysis process so as to make said operation means perform the single operation analysis process; a second step for setting, based on results of analysis for each single operation analysis process, operation conditions for performing a next analysis process; a third step for making said operation means perform the next operation analysis process using thus set operation conditions; and a fourth step for repeating said second and third steps until a predetermined completing condition is satisfied, during the execution of said fourth step, said operation analysis being temporarily stopped when a temporary stop signal is received, said operation conditions of said operation being permitted to be altered during the time when said operation is temporarily stopped, and the execution of said forth step then being restarted based on thus altered operation conditions when an operation restarting signal is received. ### Claim 8 (depends on 7) A method for calculating a physical behavior by using an operation system according to claim 7, wherein results of said operation analysis can be traced back by an arbitrary number of steps during the time when the operation is temporarily stopped and then, when said operation restarting signal is received, the execution of said fourth step is restarted based on the results of the operation analysis traced back by said arbitrary number of steps and said altered operation conditions.
