The phrase "a physical step" is correct and usable in written English.
It can be used to refer to a tangible action or movement taken in a process or procedure.
Example: "To complete the experiment, the first physical step is to gather all necessary materials."
Alternatives: "a tangible action" or "a concrete measure".
For example, you can take a physical step back from someone you're having an argument with.
You can do a lot with that piece of paper – burn it, throw it away, toss it into the wind, place it on a paper boat and send it down a river, bury it, and so forth – anything that makes you take a physical step to change things and move away from what happened to bring on the grudge.
Since the UGKS is a direct modeling method and its physical solution depends on the mesh resolution and the local time step, a physical time step needs to be fixed before using an implicit iterative technique with a pseudo-time marching step.
The poet, for example, may describe the ascent of a hill in such a way that each physical step corresponds to a new stage in the soul's progress toward a higher level of existence.
We have utilized a substrate known to be limited by a chemical rather than physical step; nevertheless, there are two chemical steps in the KSI reaction, and it is possible that the rate-limiting step changes with different mutations, an interesting and potentially informative possibility that is not addressed in this study.
A few physical steps are best, but sometimes we must improvise.
Using standard explicit integrators leads to a physical time step of sub-pico seconds, which is often two orders of magnitude smaller than the fastest physical time scales.
Firstly a physical gelation step (i.e. modulation of temperature and pH) was used to fix a specific shape; then photo-initiated cross-links were formed to increase the stiffness.
Next, through a physical analysis step that tests the flying condition and determines the optimal size, the approximated shape is flattened into 2D patches, which can be printed out and glued together to form the airbag.
Bars show the elapsed time for the dynamical step, the physical step, and the communication (data transfer) step.
Additionally, using this system we were also able to show the physical step response of the ultracapacitor.
