<div dir="ltr"><div><div><div>Hi,<br><br></div>The Catalyst live mode is still beta functionality. The client does connect to the Catalyst enabled simulation directly. You have to keep in mind that there's a pipeline on the server and a separate pipeline on the client. Essentially the pipeline on the client uses the requested filter output from the server and uses that as the source. The pipeline on the server branches of the 'catalyst:' server (instead of the eyeball it will have a circle with an intersecting triangle on the left). You can click on that icon to download that data to your client. You should be able to add in other filters on the Catalyst server by selecting the desired filter to chain off of in the Pipeline Browser and then choosing the desired filter in the menu. <br>
<br></div>If I remember correctly, the initial pipeline helps set up the environment on the Catalyst server to work with. For big simulations, you wouldn't want to download the full data set to the client anyway. <br>

<div style="line-height:21px;color:rgb(68,68,68);font-family:'Microsoft YaHei UI','Microsoft YaHei',宋体,Calibri,sans-serif;font-size:15px">In my understanding, the simulation is modified to call Catalyst library which can get pre-processed information from a python script file. The simulation also connects to paraview client directly. It means that there is no pvserver, instead, the simulation calls Catalyst library which based on paraview lib and VTK lib to process data like pvserver, is that correct? </div>
<div style="line-height:21px;color:rgb(68,68,68);font-family:'Microsoft YaHei UI','Microsoft YaHei',宋体,Calibri,sans-serif;font-size:15px">But in live mode, if I modify the paraview pipeline through the Paraview client, for example, add a filter, how to inform the simulation that the pipeline has been changed? If the simulation can be noticed of the modified pipeline, why do we need to create a python script to describe the pipeline at the beginning?</div>
