ParaView should have a "AddTimeSteps" filter to provide dummy time steps in a static dataset.
Many filters in ParaView can only be used with temporal dataset providing a TIME_STEPS information. One may want to use these filters with static dataset. A typical use-case would be the ParticleTracer filter.
Adding a filter that generates time steps for a static input would make sense and resolve this usecase.
The current workaround for this is to manually create a .pvd file or .json file pointing to a single dataset multiple times, which is a huge IO overhead and unpractical anyway.
