Why Moving load results not matching with hand calculation?

When the moving load tracer feature is used, the max and min moving load cases represent the positive and negative output respectively. 
Now, we were checking the MVmax case. Hence, the output was positive at i end of element no. 66. If this particular position is converted into a static load case and then its shear diagram is checked, the results are as below.

To create the static load case, follow the steps as shown in the image below.


Actually, its the moving load analysis control options that is causing only 1 axle to act. Kindly refer the image below for the option being used in the model that was sent to us.


When the influence line dependent option is selected, if the result being checked is for Maximum, only the positive Influence zone loads are converted into static loads. 
 The loads reducing the worst effects are not converted into static load. For element 66 at I end and for shear due to max moving load case, the worst effect is caused only by second last axle of the vehicle while the last axle relieves this effect. Hence when converting into static load case, only 1 axle loads are added. The last axle is ignored.

If this is not the way it is required, kindly use the other option (All Points) in the Load point selection. Once this is done, the results would be as per your expectations.

More details on these options could be referred to in the online help manual (Link).
