We have, let`s &nbsp;&nbsp;&nbsp;say 108 s in total to be the time of the test, and the measurements are 1000. However, when I input the number 1000 in Number of Steps, &nbsp;&nbsp;&nbsp;a question mark appeared in the Analysis Settings of the Project tree on the left side, which means that it consider this wrong and the &nbsp;&nbsp;&nbsp;study cannot run, appearing red icons on the left of the Inputs I have selected for the Solution.<\/p>\n<p><\/p>\n<p>&nbsp;&nbsp;&nbsp;When I input the the Number of Steps to equal to 1, the simulation works correctly and I can have the results of the analysis I have set &nbsp;&nbsp;&nbsp;(image 1). But my test is dynamic and the time step 1 does not indicates this in modelling.<\/p>\n<p><\/p>\n<p>I have tested different values for the Number of Steps, but it does not accept other than 1 in this case to run the analysis.<\/p>\n<p><\/p>\n<p>Could you assume why this is happening?
