I would like out to export out a Smoke Trail simulation as a VDB sequence so I can import it in a different package. Because the smoke is clustered I can't figure out how to export it out. It only seems to export out one cluster. Setting $CLUSTER in the Rop Output path doesn't do anything. I think that variable is used if you distribute the sim on different machines. I only have 1 machine. Redshift displays there are multiple density channels and the file size of each frame get larger even though the displayed cluster is empty on further frames. I'm using the Smoke Trail shelf preset as a starting point. Eventually I'd like to simulate a long smoke trail along a moving object. Unfortunately I couldn't find any information about this. I'm using Houdini Indie. Thank you for your time.

Thank you guys so much! Both provided solutions work perfectly.

Hi guys I'm new here. First of all I wanted to thank you for having such an awesome community. I'm pretty new to houdini, but have learned a lot by lurking on this forum. I would like to create a spiraling curve(like a phone cord) from another curve(not a straight curve). I already saw some other solutions by just making a helix and deform that along the curve. I also saw a solution about making an arc and sweeping that on a curve and later join the pieces together. I was wondering if there would be a more procedural/mathematical way by using the curve and a point vop or point wrangle? Maybe with a cross product and using the point number as a variable to control the twists? Unfortunately my math knowledge is pretty basic. I would be very happy if someone could post a sample.
