I am not able to find the right options to change the smoothing length constant as a beginner. Do help me out.

If you insert a Section object from the LSDYNA Pre tab and scope the section to a particle body, the SPH Controls section appears in the Details panel and includes 3 parameters as shown in the figure below:

How to insert a Section object from the LSDYNA Pre tab ?
Can you please elucidate with some pictures or sentences ?
Thanks.

Step 1: First click on LS-dyna in tree, then you will see LSDYNA Pre tab.
Step 2: Click on LSDYNA Pre, then click on Part in ribbon area.
Step 3: Under PART you will find section option. Click on it to insert section.
Step 4: Under details of section, you will see SPH controls.

I want to change the smoothing length constant of SPH meshing in Autodyn solver instead of LS-Dyna.
I adopted this to validate a research paper, where they mentioned that they used ANSYS Autodyn solver and gave a smoothing length of 0.5 mm.
Could you please help me out ?

You can use it with Ansys Autodyne solver. Transfer the model to Autodyne system(as shown in image)
Now, under Parts>SPH part>solver setting>solution you can get the options for smoothing length.
I have also attached the Ansys help link for your help.
